Our new body, we may be sure, will match and perfectly express our perfected new heart, that is, our renewed moral and spiritual nature and character. That body will reflect us as we were at our best rather than as we are physically at the time of leaving this world. Indeed, we should expect it to be better than our physical best ever was. The new body will never deteriorate, but will keep its newness for all eternity. It will know no inner tensions between one desire and another, each pulling against the other, nor will desire to do something ever outrun energy and ability to do it. Nor, when we are in glory, shall we ever lack, or fail to show, love to the Father, the Son, and the Holy Spirit, and to all the brothers and sisters in Christ who are with us there.
