More effect leading to cause. If true conviction(Godly sorrow...see 2 Corinthians 7:10...)has been wrought, it is a sign the Spirit has already been at work within the sinner. Ppl don't show contrition to their mortal enemy.
He is working through conviction but not regeneration. That is the sticking point in this, regeneration, what is regeneration in your definition?
Most say it is rebirth, being born again. Now if a person is reborn before faith then we have a scriptural problem.
John 3:
"15 That whosoever believeth in him should not perish, but have eternal life.
16 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 regeneration rebirth to eternal life with God to occur it states in verse 15 whosoever believeth in Him has eternal life, that life came that is the rebirth comes by believing, other wise it would state, He who has bee born can believe. Scripture doesn't say that, the gift of salvation that is the new life the regenerated life comes as we see in Acts 11:17 "Forasmuch then as God gave them the like gift as he did unto us, who believed on the Lord Jesus Christ; what was I, that I could withstand God?" to those who believed on the Lord Jesus Christ.
Romans 4:
"20 He staggered not at the promise of God through unbelief; but was strong in faith, giving glory to God;
21 And being fully persuaded that, what he had promised, he was able also to perform.
22 And therefore it was imputed to him for righteousness.
23 Now it was not written for his sake alone, that it was imputed to him;
24 But for us also, to whom it shall be imputed, if we believe on him that raised up Jesus our Lord from the dead;
25 Who was delivered for our offences, and was raised again for our justification."
How did Abraham receive the new life that is rebirth and stand as righteous before God, he believed, he was fully persuaded and staggered not at God's promise and therefore because of that belief He had righteousness imputed to him. To be reborn (regenerated) and have eternal life we must have a right standing with God, does that right standing come before we believe or after? Does rebirth occur before or after faith? What does scripture state gives us eternal life that is the new birth which is regeneration? It appears the definition of regeneration may be the more telling issue, what is regeneration in your view?
John 6:
"53 Then Jesus said unto them, Verily, verily, I say unto you, Except ye eat the flesh of the Son of man, and drink his blood, ye have no life in you.
54 Whoso eateth my flesh, and drinketh my blood, hath eternal life; and I will raise him up at the last day.
55 For my flesh is meat indeed, and my blood is drink indeed."
Do we eat His flesh and drink His blood before we have faith or after? Those who receive HIM through faith have life but until they receive Him that is eat His flesh and drink His blood they have no life they are not regenerated until they have done that!
