But God, who is rich in mercy, for His great love wherewith He loved us, Even when we were dead in sins, hath quickened us together with Christ, (by grace ye are saved;) And hath raised us up together, and made us sit together in heavenly places in Christ Jesus… – Ephesians 2:4-6

O marvellous death of Christ, how securely dost, Thou set the feet of God’s people on the rocks of eternal love; and how securely dost Thou keep them there! Come, dear brethren, let us suck a little honey out of this honeycomb. Was there ever anything so luscious and so sweet to the believer’s taste as this all-glorious truth that we are complete in Him; that in and through His death and merits we are accepted in the Beloved? Oh, was there ever anything more sublime than this thought, that He hath already raised us up together, and made us sit together in heavenly places in Christ Jesus, far above all principalities and powers; just where He sits? Surely there is nothing more sublime than that, except it be that a master-thought stamps all these things with more than their own value, that master-thought that, though the mountains may depart and the hills be removed, the covenant of His love shall never depart from us. “For,” saith Jehovah, “I will never forget thee, O Zion;” “I have graven thee upon the palms of My hands; thy walls are continually before Me.” O Christian, that is a firm foundation, cemented with blood, on which thou mayest build for eternity! Ah, my soul! thou needest no other hope but this. Jesus, Thy mercy never dies; I will plead this truth when cast down with anguish, Thy mercy never dies. I will plead this when Satan hurls temptations at me, and when conscience casts the remembrance of my sin in my teeth; I will plead this ever, and I will plead it now,-

“Jesus, Thy blood and righteousness
My beauty are, my glorious dress.”
