“Yet even now,” declares the LORD, “return to Me with all your heart, with fasting, weeping, and mourning.” So rend your hearts and not your garments, and return to the LORD your God. For He is gracious and compassionate, slow to anger, abounding in loving devotion. And He relents from sending disaster.
There is no marker on the road away from God that reads "too far." The voice in your head may disagree. It says you have been gone too long, done too much, or stopped believing for too many years to simply turn around now.
