The practicality of Christian salvation is one of the greatest evidences of its truth. Think about it. All the other religions in the world require you to do certain things to gain salvation. You have to accomplish sinlessness on your own. The god, or gods, tell you what you are supposed to do, but it is your responsibility to carry it out. Once you accomplish this, you gain eternal life.
But is that really practical? Look at the Pharisees. Outwardly, they were really good at not sinning. But because of that, they were inwardly prideful. They couldn't actually become free from sin, because by accomplishing the feat of abstaining from outward sins, they then fell prey to the inward sin of self-righteousness.
They earned it. And the person next to them didn't. They were really good at self control. But self control, without grace, leads to pride.
Christianity provides a religion where the receiver of salvation doesn't earn it on their own. They can't. Salvation is provided by God. It's a free gift. One that can't be earned.
By receiving salvation this way, one can't become prideful. That person had nothing to do with it.
And not only can they not become prideful, but they become more valuable. This salvation was given to them, and it didn't have to be. It was given to them by the Creator of the universe. The one the standard of morality they have failed to meet is based on. The fact that the God of the universe values them enough to give them this amazing gift - and the fact that it costed Him so much to give it - brings enormous worth to the individual.
So we see that Christianity provides a remarkable balance that cannot be achieved by any other religion. You can't become prideful, because you didn't do it on your own. And you can't be depreciated, because you are valuable enough to be given the gift.
It turns out that while we don't really understand why God would decide to allow us to have this free gift, it really makes sense. In fact, it is the only salvation method that does.
This provides good reason to accept it. Not necessarily a knockout argument, but a clue to the truth of the Christian message.
