I thought you might be interested in reading this and giving it some thought.
I asked my father one time, “Was Jesus sinless before the Son of God came and took up his abode in Mary’s Son at the Jordan River?” His reply? “It doesn’t matter.” Amen! It doesn’t matter what you or I were, either, or how we lived before the Son of God took up his abode in us! Thank God!
Here is the comment I added (as a footnote) to the Father and Son book today:
Even if a man had offered up his son as a sacrifice for the world’s sins, it would have been unacceptable to God because all humans, including Mary’s son Jesus, are sinful by nature, which would have made the sacrifice unacceptable. Only God’s Son was sinless, both before he came to earth and afterwards.
