That last verse is one of the most amazing verses in the whole letter. The picture presented to us is Christ the head, the church his body.
When you think of eternal glory, when you think of heaven, do you sometimes think, ‘If only I could really believe that at death I will be ushered in to a new dimension of experience and knowledge, eternal glory. I believe it, but if only I could feel it, if only I could believe it with all my heart.’ Well, that is vital to the Christian, and that is what the apostle is ministering to us here. This is why he comes to this subject of the power of God. If you can see the mighty power of God so much like the resurrection of Christ himself, bringing life out of death, transformative in the extreme; if only you can see what has happened to you, that you would never have been like this but for the mighty power of God. I am an ailing Christian, you may say, and I stumble and fall, but I would never have the understanding that I have as a Christian without God. I would never have the conscience that I have, I would never have the desires and the strivings that I have, let alone the answered prayer and the experiences that I have. This is the mighty power of God that raised Christ from the dead, that resuscitated in the ministry of Christ, the widow’s son at Nain, that raised and resuscitated the daughter of Jairus, that raised from four days in the grave Lazarus of Bethany. And even more, that raised Christ from that death of deaths. And my conversion and my maintenance as a Christian and my ongoing sanctification is a miracle of life like that. I see it now, I see the size of it, the scope of it, the wonder of it, the magnificence of it. Oh, how much easier it is for me to believe. If I lay down my head tonight for the last time, I shall awake in glory in the reception hall of the King of kings and Lord of lords, with wonderful sights and amazing joy and peace. How much easier to believe when I see what God has already done and what he is doing.
