1 John 1:5-10
5 This is the message he has given us to announce to you: God is light and there is no darkness in him at all. 6 So we are lying if we say we have fellowship with God but go on living in spiritual darkness. We are not living in the truth. 7 But if we are living in the light of God’s presence, just as Christ is, then we have fellowship with each other, and the blood of Jesus, his Son, cleanses us from every sin. 8 If we say we have no sin, we are only fooling ourselves and refusing to accept the truth. 9 But if we confess our sins to him, he is faithful and just to forgive us and to cleanse us from every wrong. 10 If we claim we have not sinned, we are calling God a liar and showing that his word has no place in our hearts.

Why do we need to confess our sins if all sin was forgiven on the cross?  All people are sinners by nature and by practice.  At conversion all our sins are forgiven–past, present, and future.  Yet even after we become Christians, we still sin and need to confess.  This kind of confession is not to gain God’s acceptance but to remove the barrier that our sin has put between us and Him. The truth is that sin breaks our fellowship with God.  So even though we are redeemed and on our way to be with Him forever, we are still in a sinful world giving in to sin.  When we come before Him in prayer, we need to confess our sin, so we can have complete fellowship with Him.  Bringing our sin before Him, makes us think about it and therefore gives us wisdom to remove it from our lives.  God cannot be in darkness and sin is darkness, so we must remove all darkness from our lives before He can have fellowship with us.  This does not mean that we must confess every sin before we die so we can be with Him.  We are covered by the Blood of Christ and will be with Him if we believe Him.  But to have fellowship with Him in this world we need to remove the darkness because God is light and there is no darkness in Him at all.  So if we want to be with Him, we need to remove the darkness.  And we know that growth only happens in the light.  A plant will not grow without light and neither will we grow in Christ while in darkness.  If His Word has a place in your heart, you will grow by being in His presence because He is Light.  Darkness can not exist in the Light, so confess and remove all darkness so you can have fellowship with Him.

Have a God Day!
