On the other hand, if you do believe in God, then you are faced with the question of who He is. Is he the grandfatherly bearded man that many people think of, sitting on an ancient throne in Heaven. Is He an amorphous presence, wisping around the universe; sort of a cosmic spy, eavesdropping on things that humans do? Is He an angry, vengeful God, as many people who have read a bit of the Old Testament believe? After all, he turned Lot’s wife into a pillar of salt, and caused the big fish to swallow Jonah. Or, is He a personal God; a vibrant omnipotent, omnipresent God who desires to have a relationship with each of us?
I believe in the latter. I believe it because my life is living proof of it. The bottom line is that I know what I was like before I accepted Christ and I know what I am like now. This radical change can only be explained by the intervention of the most loving God imaginable. My life is the evidence of Jesus. I know what I was like before I began to trust in Him, and I know what I’m like now. And the “now” me is definitely better. I am still a very imperfect creature, but I continue to grow, mature and develop in such a way that convinces me of God’s presence and love for me.
I have made plenty of mistakes in my life and continue to make them. My Christian walk has been full of misfires. My experience is probably the most common among Christ-followers: a struggle with sin, repentance, forgiveness in an ongoing way as part of my lifelong journey. However, the more I trust in Him, the less likely I am to make mistakes. And I make fewer mistakes now than before. The change in my life is the most convincing evidence of the truth of Christianity to me.
When we follow Jesus, our lives are so radically changed that there is no human explanation for it. The only explanation is that something supernatural has happened to us. The proof in the proverbial pudding is in the eating. Christianity works. People’s lives are dramatically changed for the better. And I believe that Christianity stands alone in this way among a plethora of religions, psychotherapy, and self-help doctrines. Christianity is the world’s biggest belief system because it works.
Some people who are introduced to the gospel of Jesus Christ decide not to become Christians. Others fall away from the faith quickly. They mistakenly believe that they don’t measure up. In other words, they don’t believe that they are good enough to become Christians. However, no one measures up. Christians don’t measure up. We are all sinners and don’t deserve what God has done for us by way of the Cross. Only Jesus measured up. That’s why He was the perfect sacrifice. He didn’t deserve it, and yet he submitted to it. Its exquisite unfairness makes it incredibly just.
Some people decide against Christianity because of what they believe to be the hypocrisy of Christians. They judge the validity of Christianity based upon the actions of Christians. If it doesn’t work for them, they reason, then it certainly won’t work for me. But Christian growth is a lifelong process. And you will encounter Christians who are in various stages of Christian growth. Some live close to sinless lives, thanks to the work of the Holy Spirit. Others continue to grow in their faith walk. But all are ultimately headed for the same destination.
Some people simply decide that for them, Christianity isn’t worth the investment. They believe that Jesus was who He said He was. They believe He is the way to Heaven. But they simply decide that Christianity isn’t worth it. It’s too much work. They are just too comfortable where they are. They don’t want to give up certain behaviors, or decide that praying, studying the Bible and going to church just isn’t worth the hassle. Even more tragic are the folks who believe that they can always change their minds later. Maybe they eventually get around to it. But some don’t.
Even non-Christians understand the concept of walking the talk. It is a basic Christian idea that faith without action is meaningless. Our beliefs are reflected in our lives. We study God’s Word, in order to get better acquainted with Him. We go to church because we want to worship Him. And although that first tee is beckoning on a beautiful Sunday morning, we do what we believe He wants us to do. Christians who pray regularly, study the Bible and go to church somehow end up with stronger faith and better blessings. The more we come to learn who Jesus is, the more we want to learn about Him. And the more daily faith we have in Him, the better our lives become.
At its core, Christianity is the simple step in faith of a nine year-old boy who acknowledges that Jesus died for his sins. But we execute upon this faith with another kind of faith; an ongoing faith in our daily lives. We believe in the power of Jesus to transform our lives, every step of the way. In doing so, we relinquish it all to him; our fears, our ambitions, our sin, our lives. The sooner we allow it, the faster our lives are transformed.
And this is where the concept of faith becomes critically important. We take that first step of faith by a simple belief, but we take the next step of faith and the step after that by allowing Him to miraculously transform our lives. And the best part is that if we continuously engage in those steps of faith throughout our lives, He is incredibly and perfectly faithful to do everything that He promised to do for us.
