John 8:31

[31]Then said Jesus to those Jews which believed on him, If ye continue in my word, then are ye my disciples indeed; Matthew 7:20-23

[20]Wherefore by their fruits ye shall know them.

[21]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.

[22]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?

[23]And then will I profess unto them, I never knew you: depart from me, ye that work iniquity. James 1:22

[22]But be ye doers of the word, and not hearers only, deceiving your own selves. 2 Peter 1:10

[10]Wherefore the rather, brethren, give diligence to make your calling and election sure: for if ye do these things, ye shall never fall:. 2 Corinthians 13:5

[5]Examine yourselves, whether ye be in the faith; prove your own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates? Matthew 7:13-14

[13]Enter ye in at the strait gate: for wide is the gate, and broad is the way, that leadeth to destruction, and many there be which go in thereat:

[14]Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it.
