To whom be glory for ever and ever. Amen. – Galatians 1:5

God is glorified in Christ’s death. Has the Father given His Son, Jesus Christ, to die for us? Then there is glory enough in Jesus Christ upon the cross to last throughout eternity. Fix your eye upon that bleeding Savior; behold the glorious justice of God in laying guilt on Him, and punishing it on Him, and behold also the inconceivable love of God in thus putting His Only-begotten to death that we might live through Him. You need not range the world around to see the glory of God in nature, though that is a delightful employment, for there is enough glory in the cross of Christ to last throughout all eternity. The apostle says, “To whom be glory for ever and ever.” How long that is, I cannot tell. “For ever” is without any end, but Paul says, “For ever and ever,” and there is glory enough in the cross of Christ to last for ever and ever, as long as the Eternal Jehovah Himself exists.

Well then, has Jesus Christ delivered us from the world? Have we fled to Him, and been pardoned? Are we accepted in the Beloved? Then, let us begin to glorify God now. Let us glorify His dear Son, let us praise Him. Let every beat of our heart tell out our joyous thankfulness, and so continually yield sweet music unto God…for it is indeed a subject of great praise to be separated from the world, and to be made holy unto the Lord. But, brothers and sisters, when you once begin the music, never leave off, because, as the apostle says, glory is to be given to God “for ever and ever.” I saw, last week, a brother from the backwoods of America, and he said to me, “Twenty years ago, I was in your vestry, and you did me much good by something that you said to me.” I asked, “What did I say?” And the good man replied, “You said, ‘Brother, as a minister, there are two occasions upon which you ought to preach Jesus Christ.’ I enquired, ‘What are those two occasions?’ You answered, “In season, and out of season.'” Well now, there are two occasions upon which we ought to praise God, “in season, and out of season.” Praise Him when you feel like praising; and when you do not feel like it, praise Him till you do. ~ C.H.
