I would like to hear about the doctrine of forbearance, specifically in Romans 2 and 3. Do you reject that God was forbearing in the sin of His people before Christ came to expiate sin and propitiate God's wrath?
God has never hated those in Christ because He was forbearing with their sin until the death of the testator. If Christ did not come to die on the cross, His people would be left in their sin.
Or despisest thou the riches of his goodness and forbearance and longsuffering; not knowing that the goodness of God leadeth thee to repentance?
Romans 2:4 KJV
Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God;
Romans 3:25 KJV
Fear not; for thou shalt not be ashamed: neither be thou confounded; for thou shalt not be put to shame: For thou shalt forget the shame of thy youth, and shalt not remember the reproach of thy widowhood any more.
For thy Maker is thine husband; the Lord of hosts is his name; and thy Redeemer the Holy One of Israel; The God of the whole earth shall he be called.
For the Lord hath called thee as a woman forsaken and grieved in spirit, and a wife of youth, when thou wast refused, saith thy God.
For a small moment have I forsaken thee; but with great mercies will I gather thee.
In a little wrath I hid my face from thee for a moment; but with everlasting kindness will I have mercy on thee, saith the Lord thy Redeemer.
For this is as the waters of Noah unto me: for as I have sworn that the waters of Noah should no more go over the earth; so have I sworn that I would not be wroth with thee, nor rebuke thee.
For the mountains shall depart, and the hills be removed; but my kindness shall not depart from thee, neither shall the covenant of my peace be removed, saith the Lord that hath mercy on thee.
Isaiah 54:4-10 KJV
