We have all sinned. We were all created to have a personal relationship with God, because we all choose to go our own independent way, our relationship with God was broken. The fact that we are selfish and self-centered is obvious because we either rebel against God or don't really care about Him. We are cut off from God. A great gap cuts us off from God because He cannot tolerate sin.
People often try to find a full and meaningful life through their own efforts.
They try to live a good life or be religious. But the Bible clearly teaches that there is only one way to bridge this gap. Jesus Christ is God's only cure for our sin. Through Him you can know God personally and experience His love. Jesus died in our place.
