He who does not love does not know God, for God is love. 1 John 4:8
The Greek word for love, agape is by far the one that appears most frequently in the New Testament. Agape means to love the undeserving, despite disappointment and rejection. If we are the children of God, then we must love others they way God has loved us, even if they seem unlovable.
I just read your intro. I am excited that you are a Jewish believer. Through DNA studies both my wife and I, but her especially have huge Jewish ancestry. We feel blessed!
What a blessing to have both a natural ancestry dating back to the patriarchs (Abraham, Isaac and Jacob), as well as being a born-again child of God and spiritual seed of Abraham who have been grafted in and partakers of a covenant relationship with the God of Israel.
