Jesus, the only begotten Son of God says: “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]” (Matthew 7:21).
“For many are called, but few are chosen” (Matthew 22:14).
When Jesus was here on this earth going about doing his Father’s business, he was asked by his disciples, “What shall we do, that we might work the works of God?” (John 6:28).
“Jesus answered and said unto them, ‘This is the work of God, that ye [BELIEVE ON HIM WHOM HE HATH SENT]’” (John 6:29).
“For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. For God sent not his Son into the world to condemn the world; but that the world through him might be saved” (John 3:16-17).
“‘[BELIEVE ON THE LORD JESUS CHRIST, AND THOU SHALT BE SAVED, AND THY HOUSE]’” (Acts 16:31).
“He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God” (John 3:18).
“But what saith it? The word is nigh thee, even in thy mouth, and in thy heart: that is, the word of faith, which we preach; That 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]. For with the heart man believeth unto righteousness; and with the mouth confession is made unto [SALVATION]” (Romans 10:8-10).
“For as the Father raiseth up the dead, and quickeneth them; even so the Son quickeneth whom he will. For the Father judgeth no man, but hath committed all judgment unto the Son: That all men should honour the Son, even as they honour the Father. He that honoureth not the Son honoureth not the Father which hath sent him.
Verily, verily, I say unto you, He that heareth my word, and believeth on him that sent me, hath everlasting life, and shall not come into condemnation; but is passed from death unto life” (John 5:21-24).
