Too far gone? I don’t think so, not while our God is on the Throne!
“Let the wicked forsake his way and the unrighteous man his thoughts; let him return to the Lord that He may have compassion on him, and to our God, for He will abundantly pardon” (Is. 55:7).
This verse overflows with the grace and mercy of God. It is an invitation, not for good and righteous people to come, but it is an offer of pardon for the wicked and the unrighteous. There is not one person in this world who is “to bad” for the grace and mercy of God to change. So never view any unbeliever as a lost cause. Never think that the grace of God is too small for them. If they will turn to Him, then He will show them compassion.
So keep praying, keep sharing the message of Christ, and trust that there is always hope!
