Many children fooled into believing Santa Claus is real think that they're good enough. It's because they get their presents and they think that Santa Claus and not their parents left the gift. To the child, Santa Claus is very real. That's where most parents are very wrong to think that it's just a white lie. No, it's not a white lie and parents lying about Santa Claus lose their credibility when they tell their children that they never taught them to lie. Worse, they say that it's just a white lie when they're confronted for giving their children false hope. Tell someone God isn't real not so many lose their minds. Tell somebody that Santa Claus isn't real and expect chaos.
Santa Claus theology only measures good works against bad works. God's standard is much different than Santa Claus theology. James 2:10-11 says that God demands absolute sinless perfection if you expect to work for your salvation. Romans 3:19 declares we've all been bad not good. Santa Claus theology demands you work for your salvation. Jesus Christ came to save the people from their sins (Matthew 1:21) because men are incapable of doing so. 1 Corinthians 6:11 shows that a truly sanctified life is only possible by the Holy Spirit. Titus 2:11-14 shows that only true grace from God makes a person do good. That's much different than trying to do all the good you can in hopes of winning salvation.
Since today is Christmas Eve it's time to ask the question. What's the reason why you celebrate Christmas? Even if Jesus wasn't born on December 25 but I'm thankful for this fact. Jesus gave up His glory and became a child born in a manger. He didn't come for His earthly ministry as a king but as a poor man from a carpenter's household. Santa Claus theology offers no grace and no hope - you're on your own. Jesus offers forgiveness and new life for the naughty ones while Santa Claus theology only crosses them out. Christmas should be a reminder that Christ came into this world not because we're good but because we've been bad and only He can make us good.
