If we could save ourselves why would we need a Savior? Jesus didn’t enter the world to help us save ourselves. He entered the world to save us from ourselves. As a Boy Scout, I earned a lifesaving merit badge. Fact is, the only people I saved were other Boy Scouts who didn’t need to be saved. During training I would rescue other trainees. We took turns saving each other, but since we weren’t really drowning we resisted being rescued. “Stop kicking and let me save you,” I’d say.
It’s impossible to save those who are trying to save themselves. You know, you might save yourself from a broken heart or going broke or running out of gas. But you’re not good enough to save yourself from sin; you aren’t strong enough to save yourself from death. You need a Savior, and because of Bethlehem, you have one!
