What in the world does God need to overcome? He could overwhelm anything and anyone, except that He does not violate our freedom. He then overcomes our perceptions of Him with the presence and life of Jesus; so that we might know God for who He is. He overcomes our anxieties about who we have been, who we will be, and if it is good enough with mercy and love from the cross of Jesus; so that we might know rest in Him. He also overcomes our judgment of ourselves and others with forgiveness; so that we might forgive and be forgiven.
He is truly and overcoming God, who waits for our barriers to come down; so that we might know Him, receive mercy and love, and know forgiveness.
