Sometimes the weight of our sin can weigh us down to the point that we question our salvation.
All of us have things in our past that are now fully repulsive to us. We wish so much that we could have a redo and blot that thing out of our lives. And, of course, this is precisely what Jesus offers us. He takes our ugliness and our sin from us and nails it to His cross, then He offers us a new life in Him.
