I say the truth in Christ, I lie not, my conscience also bearing me witness in the Holy Ghost, that I have great heaviness and continual sorrow in my heart. For I could wish that myself were accursed from Christ for my brethren, my kinsmen according to the flesh… – Romans 9:1-3
I wish all felt it, but there are generally some in every church who will never warm up to the right point. If we could once get the whole Church up to blood heat, we might be content. I never want you to get to fever heat, but to blood heat—the heat of the blood of Christ—to love as He loved! Oh, to get there and to stay there! Well, what would be the result, if we all felt as Paul did? The first effect would be likeness to Christ! After that manner He loved—He did become a curse for us! He entered under the awful shadow of Jehovah’s wrath for us. He did what Paul could wish but could not do. He passed under the awful sword that we might be delivered from its edge forever!
Brethren, I want you to feel that you would pass under poverty if you could save souls better by being poor! That you would gladly endure sickness if from your sick bed you could speak better for Christ than now! Yes, and that you would be ready to die if your death might give life to those dear to you! …Oh, to be willing to die if others may be saved from the eternal death! God give us just such a spirit as that! This should be our constant feeling—how else can we become like Christ? …When the Spirit of God has brought you to it, you will pray day and night for those whom you love! As you go down the road, something will suggest your praying for them. The very oaths and blasphemies so common in our streets will make you pray for sinners. A gracious meeting where some are saved will move you to prayer. A thousand things will lead you to pray, and that prayer will lead you to effort—to proper and fitting effort. It is wonderful how a man can talk to souls when he loves them! ~ C.H. Spurgeon
