The Scriptures have much to say about walking with God. In the garden of Eden, humanity’s first home, God walked with Adam and Eve. They wanted to be with Him, listening carefully and enjoying His presence. When they sinned it all came to a screeching halt. Now the thought of being with God scared them, so they hid (Genesis 3:8-9). God’s intention was broken because sin cannot be in the presence of the Holy One, and the wages of sin is death (Genesis 2:16-17; Romans 6:23). When sin entered the world spiritual death became immediate and the process of physical death began. Humanity was forced out of Eden and doomed to long for a relationship with God that could no longer be. It would never be unless God in His mercy intervened to make a way.
That is precisely what God did through Jesus. By His death on the cross He made a way for sin to be atoned for and relationship with God to be restored, a way for us to walk with God through life and into eternity.
