Let the Bible Speak for Itself: “Not everyone who says to Me, ‘Lord, Lord,’ shall enter the kingdom of heaven, but he who does the will of My Father"

21 “Not everyone who says to Me, ‘Lord, Lord,’ shall enter the kingdom of heaven, but he who does the will of My Father in heaven. 22 Many will say to Me in that day, ‘Lord, Lord, have we not prophesied in Your name, cast out demons in Your name, and done many wonders in Your name?’ 23 And then I will declare to them, ‘I never knew you; depart from Me, you who practice lawlessness!’..." - Jesus, Matthew 7:21-23 (NKJV)

23 Then one said to [Jesus], “Lord, are there few who are saved?” And He said to them, 24 “Strive to enter through the narrow gate, for many, I say to you, will seek to enter and will not be able. 25 When once the Master of the house has risen up and shut the door, and you begin to stand outside and knock at the door, saying, ‘Lord, Lord, open for us,’ and He will answer and say to you, ‘I do not know you, where you are from,’ 26 then you will begin to say, ‘We ate and drank in Your presence, and You taught in our streets.’ 27 But He will say, ‘I tell you I do not know you, where you are from. Depart from Me, all you workers of iniquity.’ 28 There will be weeping and gnashing of teeth, when you see Abraham and Isaac and Jacob and all the prophets in the kingdom of God, and yourselves thrust out. 29 They will come from the east and the west, from the north and the south, and sit down in the kingdom of God. 30 And indeed there are last who will be first, and there are first who will be last.” - Matthew 13:23-30

1 ...[B]rethren, we urge and exhort in the Lord Jesus that you should abound more and more, just as you received from us how you ought to walk and to please God; 2 for you know what commandments we gave you through the Lord Jesus. 3 For this is the will of God, your sanctification: that you should abstain from sexual immorality; 4 that each of you should know how to possess his own vessel in sanctification and honor, 5 not in passion of lust, like the Gentiles who do not know God; 6 that no one should take advantage of and defraud his brother in this matter, because the Lord is the avenger of all such, as we also forewarned you and testified. 7 For God did not call us to uncleanness, but in holiness. 8 Therefore he who rejects this does not reject man, but God, who has also given us His Holy Spirit. - 1 Thessalonnians 4:1-8 (NKJV)

3 But fornication and all uncleanness or covetousness, let it not even be named among you, as is fitting for saints; 4 neither filthiness, nor foolish talking, nor coarse jesting, which are not fitting, but rather giving of thanks. 5 For this you know, that no fornicator, unclean person, nor covetous man, who is an idolater, has any inheritance in the kingdom of Christ and God. 6 Let no one deceive you with empty words, for because of these things the wrath of God comes upon the sons of disobedience.
10 ...[find] out what is acceptable to the Lord. 11 And have no fellowship with the unfruitful works of darkness, but rather expose them. - Ephesians 5:3-6, 10-11 (NKJV)

Here is what is acceptable to the LORD:

5 [So put to death the sinful, earthly things lurking within you]*: fornication, uncleanness, passion, evil desire, and covetousness, which is idolatry. 6 Because of these things the wrath of God is coming upon the sons of disobedience, 7 in which you yourselves once walked when you lived in them. 8 But now you yourselves are to put off all these: anger, wrath, malice, blasphemy, filthy language out of your mouth. 9 Do not lie to one another, since you have put off the old man with his deeds, 10 and have put on the new man who is renewed in knowledge according to the image of Him who created him, 11 where there is neither Greek nor Jew, circumcised nor uncircumcised, barbarian, Scythian, slave nor free, but Christ is all and in all. 12 Therefore, as the elect of God, holy and beloved, put on tender mercies, kindness, humility, meekness, longsuffering; 13 bearing with one another, and forgiving one another, if anyone has a complaint against another; even as Christ forgave you, so you also must do. 14 But above all these things put on love, which is the bond of perfection. 15 And let the peace of God rule in your hearts, to which also you were called in one body; and be thankful. 16 Let the word of Christ dwell in you richly in all wisdom, teaching and admonishing one another in psalms and hymns and spiritual songs, singing with grace in your hearts to the Lord. 17 And whatever you do in word or deed, do all in the name of the Lord Jesus, giving thanks to God the Father through Him. - Colossians 3:5-17 (NKJV)

2 And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God. - Romans 12:2

9 Let love be without hypocrisy. Abhor what is evil. Cling to what is good. 10 Be kindly affectionate to one another with brotherly love, in honor giving preference to one another; 11 not lagging in diligence, fervent in spirit, serving the Lord; 12 rejoicing in hope, patient in tribulation, continuing steadfastly in prayer; 13 distributing to the needs of the saints, given to hospitality. 14 Bless those who persecute you; bless and do not curse. 15 Rejoice with those who rejoice, and weep with those who weep. 16 Be of the same mind toward one another. Do not set your mind on high things, but associate with the humble. Do not be wise in your own opinion. 17 Repay no one evil for evil. Have regard for good things in the sight of all men. 18 If it is possible, as much as depends on you, live peaceably with all men. 19 Beloved, do not avenge yourselves, but rather give place to wrath; for it is written,
“Vengeance is Mine, I will repay,” says the Lord.
20 Therefore
“ If your enemy is hungry, feed him;
If he is thirsty, give him a drink;
For in so doing you will heap coals of fire on his head."
21 Do not be overcome by evil, but overcome evil with good. - Romans 12:9-21 (NKJV)

12 Blessed is the man who endures temptation; for when he has been approved, he will receive the crown of life which the Lord has promised to those who love Him. - James 1:12 (NKJV)

10 "Because you have kept My command to persevere, I also will keep you from the hour of trial which shall come upon the whole world, to test those who dwell on the earth. 11 Behold, I am coming quickly! Hold fast what you have, that no one may take your crown. 12 He who overcomes, I will make him a pillar in the temple of My God, and he shall go out no more. I will write on him the name of My God and the name of the city of My God, the New Jerusalem, which comes down out of heaven from My God. And I will write on him My new name." - Jesus, Revelation 3:10-12 (NKJV)

5 “I am the vine, you are the branches. He who abides in Me, and I in him, bears much fruit; for without Me you can do nothing. 6 If anyone does not abide in Me, he is cast out as a branch and is withered; and they gather them and throw them into the fire, and they are burned. 7 If you abide in Me, and My words abide in you, you will ask what you desire, and it shall be done for you. 8 By this My Father is glorified, that you bear much fruit; so you will be My disciples. 9 As the Father loved Me, I also have loved you; abide in My love. 10 If you keep My commandments, you will abide in My love, just as I have kept My Father’s commandments and abide in His love." - Jesus, John 15:5-10 (NKJV)

28 Then one of the scribes came, and having heard them reasoning together, perceiving that He had answered them well, asked Him, “Which is the first commandment of all?” 29 Jesus answered him, “The first of all the commandments is: ‘Hear, O Israel, the LORD our God, the LORD is one. 30 And you shall love the LORD your God with all your heart, with all your soul, with all your mind, and with all your strength.’ This is the first commandment. 31 And the second, like it, is this: ‘You shall love your neighbor as yourself.’ There is no other commandment greater than these. 32 So the scribe said to Him, “Well said, Teacher. You have spoken the truth, for there is one God, and there is no other but He. 33 And to love Him with all the heart, with all the understanding, with all the soul,[h] and with all the strength, and to love one’s neighbor as oneself, is more than all the whole burnt offerings and sacrifices.” 34 Now when Jesus saw that he answered wisely, He said to him, “You are not far from the kingdom of God.” - Mark 12:28-34a (NKJV)

8 Owe no one anything except to love one another, for he who loves another has fulfilled the law. 9 For the commandments, “You shall not commit adultery,” “You shall not murder,” “You shall not steal,” “You shall not bear false witness,”[a] “You shall not covet,”[b] and if there is any other commandment, are all summed up in this saying, namely, “You shall love your neighbor as yourself.”[c] 10 Love does no harm to a neighbor; therefore love is the fulfillment of the law. - Romans 13:8-10 (NKJV)
