As a Christian, does sin separate me from God? We are often taught that sin causes a separation, a rift that can only be restored when we confess our sin. Therefore, moving forward with our life in Christ is possible only when our tie with Him can be reestablished through forgiveness. Though this view seems to make sense, it’s not actually the case.
Because sin displeases God, it can’t help but affect our relationship, often causing us to run from Him. But sin doesn’t separate us from Him! If it did, it would mean that God would have to vacate our spirit each time we sin, and then come back once we repent. This hardly seems practical, since God would have to sever the very tie so utterly necessary to overcoming sin in the first place. It would mean cutting off the very resource essential to spiritual growth.
