Matthew 7:21-23 Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven. Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works? And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
Matthew 20:16 So the last shall be first, and the first last: for many be called, but few chosen.
1 Corinthians 6:9-11 Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind, Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God. And such were some of you: but ye are washed, but ye are sanctified, but ye are justified in the name of the Lord Jesus, and by the Spirit of our God.
Ephesians 5:5-7 For this ye know, that no whoremonger, nor unclean person, nor covetous man, who is an idolater, hath any inheritance in the kingdom of Christ and of God. Let no man deceive you with vain words: for because of these things cometh the wrath of God upon the children of disobedience. Be not ye therefore partakers with them.

Luke 18:24-27 And when Jesus saw that he was very sorrowful, he said, How hardly shall they that have riches enter into the kingdom of God! For it is easier for a camel to go through a needle’s eye, than for a rich man to enter into the kingdom of God. And they that heard it said, Who then can be saved? And he said, The things which are impossible with men are possible with God.
Luke 9:62 And Jesus said unto him, No man, having put his hand to the plough, and looking back, is fit for the kingdom of God.
