Matthew 7:12-14 King James Version (KJV)
12 Therefore all things whatsoever ye would that men should do to you, do ye even so to them: for this is the law and the prophets.
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.
2 Corinthians 5:15 King James Version (KJV)
15 And that he died for all, that they which live should not henceforth live unto themselves, but unto him which died for them, and rose again.
Matthew 16:24-25 King James Version (KJV)
24 Then said Jesus unto his disciples, If any man will come after me, let him deny himself, and take up his cross, and follow me.
25 For whosoever will save his life shall lose it: and whosoever will lose his life for my sake shall find it.
