We have seen God’s mercy and wisdom: how shall we respond?

12 ^1-2 With eyes wide open to the mercies of God, I beg you, my brothers, as an act of intelligent worship, to give him your bodies, as a living sacrifice, consecrated to him and acceptable by him. Don’t let the world around you squeeze you into its own mould, but let God re-mould your minds from within, so that you may prove in practice that the plan of God for you is good, meets all his demands and moves towards the goal of true maturity.
