Having a relationship with Jesus is the most precious treasure you can ever possess. But simply knowing Jesus for yourself is not what Christ called us to. The Bible clearly teaches us that once we trust Jesus to forgive our sins and save us from a punishment that we deserve, we are compelled to share the good news with others. To make this command real in our ministry, we've crafted a series of tools to guide believers through this Circle of Ministry. One of those tools is The Exchange. Jesus is the Son of God. He came to earth, lived a perfect life, and died in our place to save you and me from our sin. When you trust Jesus to pay the price of your sin, you become a child of God - the start of a real relationship with Him. This is the cornerstone of the Bible and our ministry. We call this The Exchange - when Jesus exchanges our sinful record with his personal, perfect sacrifice.
