1:12But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name:

3:16For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.

10:9That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.

10:10For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.

1:9If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
