Now, my beloved hearers, I ask you, before I proceed, this question, Is there a heart in this congregation that has not yet rested here? Is there a heart here to-night that will say, I am not satisfied with Christ's service: I cannot rest in His work? What! The Son of God has stooped to serve you. The One who made you, the One who gave you life and breath and all things, the One to whom all are responsible, He has stooped to become your servant. It is not a question of asking you to do any thing, or asking you to give any thing, because--mark those words--they are words which sweep all through the history of the Son of Man--they are words which, in all their length and breadth and fullness, you can take up and use as if you were the only object of this service in the world--"The Son of Man is come to serve and to give." He is not come to get; He is not come to ask. The legal mind leads you to think that God is an exactor--that He is making demands upon you--that He wants your services in one way or another. But oh remember, I pray you, that your first great business, your primary and all-important work, is to believe in Jesus--to rest sweetly in Him, and in what He has done for you on the cross, and in what He is doing for you on the throne. "This is the work of God, that ye believe on Him whom He hath sent." You remember the interesting question of the Psalmist--a question asked when his eye rested on the magnitude and multitude of Jehovah's benefits--"What shall I render unto the Lord for all His benefits?" What is the reply? "I will take the cup of salvation, and call upon the name of the Lord." Is this the way to "render unto the Lord"? Yes, this is just the way that gratifies and glorifies Him. If you really want to _render_, you must _take_. Take what? "The cup of salvation"--a full and brimming cup, most surely; and as you drink of that cup, as the glories of God's salvation shine in the vision of your soul, then will streams of living praise flow from your grateful heart. And you know He says, "Whoso offereth praise, glorifieth Me." In a word, then, you must, first of all, allow your soul to dwell upon the marvelous mystery of Christ's service toward you in all the depth of your need; and the more you dwell upon that, the more will you be in the true attitude to serve Him.
