What does Acts 17:30 mean?

What if we learn we have not been following God when we thought we were? Walter Veith explains Acts 17:30 where it says that God winks at ignorance but commands everyone to repent. Walter explains that God is not watching and waiting for our failures in order to strike us down. God takes our humanity into account. All of us have fallen short of the glory of God, but we must be willing to repent, be committed to Him and be willing to be transformed into His character.
