Followers of Jesus Christ admit we blow it every single day. How is it hypocritical to freely admit that you screw up all the time and then screw up? We never claim to be perfect but are recipients of great piles of grace for the great piles of mistakes we make. The penalty for those mistakes is paid by the only God who reaches down to humankind and creates a way for us to be in deep relationship with Him.
Christianity is unique and its claims are mutually exclusive. The claims of Christianity and some other religion cannot be true at the same time. The Muslim, the Hindu and the Christian cannot each be a little bit right. God is plenty big, powerful and sufficient in the Christian faith. We don't need another god and He is not part of some larger truth.
Christianity is based entirely on Jesus' perfect life, death on a cross and resurrection from the tomb three days later. If there's no cross and no empty tomb, our faith is a sham. But there was a cross and an empty tomb. Now that presents a real problem to those who reject Christianity. What if Jesus is who He says He is?
God is personally knowable and that entrance into Paradise is guaranteed not because of my works or faithfulness but because Jesus Christ's perfect works, which are credited freely to my account with God.
There is one Supreme all Powerful God. We should not seek to achieve nirvana by imperfectly purifying yourself thru your own efforts but by relying on the perfect purifying gift of Jesus Christ. We can be sure that Jesus Christ existed in history, but the atheist or agnostic has an impossible case of proving with 100% certainty that there is no God. To them, I say that I like my faith better than yours. To my secular friends who claim God does not matter, I implore you to consider that there is something after your last breath where He does matter supremely.
Christianity works because it is true. I've bet my whole life on it. Ineffable joy awaits in heaven for those who believe.
The most important questions in life are: Who is God? Does God know you? and Do you know God? What's your answer to these questions...
