I wanted to substantiate my positions concerning salvation and eternal security with the actual scriptures. Here are the verses that instruct a person how to become a Christian:
John 3:3-7 Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God. Nicodemus saith unto him, How can a man be born when he is old? can he enter the second time into his mother's womb, and be born? Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God. That which is born of the flesh is flesh; and that which is born of the Spirit is spirit. Marvel not that I said unto thee, Ye must be born again.
Romans 3:10 As it is written, There is none righteous, no, not one:
Romans 3:23 For all have sinned, and come short of the glory of God;
Romans 5:8 But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us.
Romans 6:23 For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.
Romans 10:9 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.
Romans 10:13 For whosoever shall call upon the name of the Lord shall be saved.
1 John 1:9 If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
People do not just decide to become Christians. They must be convicted of their sins and drawn to Christ by the Holy Ghost and Father:
John 16:7-8 Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send him unto you. And when he is come, he will reprove the world of sin, and of righteousness, and of judgment:
John 6:44 No man can come to me, except the Father which hath sent me draw him: and I will raise him up at the last day.
Here are the verses that teach a person cannot become lost after being saved:
John 10:28-29 And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand. My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father's hand.
Romans 8:38-39 For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come, Nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord.
Ephesians 4:30 And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption.
Philippians 1:6 Being confident of this very thing, that he which hath begun a good work in you will perform it until the day of Jesus Christ:
