He expresses it by a conditional sentence stating that if God is for us, the outcome will surely be that none can overpower the will of God for our lives. The Apostle Paul has just described God’s salvific work in the believer’s life from election to calling, from calling to justification and from justification to glorification. He stills our heart by stating a truthful supposition.
