For He hath made Him to be sin for us, who knew no sin; that we might be made the righteousness of God in Him. Now then we are ambassadors for Christ, as though God did beseech you by us: we pray you in Christ’s stead, be ye reconciled to God. – 2 Corinthians 5:21,20
Oh, that these lips had language, or that this heart could speak without them! Then would I plead with every unconverted, unbelieving soul and plead as for my life. Friend, you are at enmity with God, and God is angry with you; but on His part there is every readiness for reconciliation. He has made a way by which you can become His friend—a very costly way to Himself, but free to you. He could not give up His justice and so destroy the honour of His own character; but He did give up His Son, His Only Begotten, and His Well-Beloved; and that Son of His had been made sin for us, though He knew no sin. See how God meets you! See how willing, how anxious He is that there should be reconciliation between you and God today. It is not from lack of kindness on His part; it is from lack of willingness on yours. The burden of your ruin must lie at your own door: your blood must be on your own skirts.
Now observe what we have to say to you today is this: we are anxious that you should be at peace with God, and therefore we act as ambassadors for Christ…I once knew Him not, neither did I care for Him. I lived well enough without Him, and sported with trifles of a day, so as to forget Him. He brought me to seek His face, and seeking His face I found Him. He has blotted out my sins and removed my enmity. I know that I am His servant, and that He is my friend, my Father, my All. And now I cannot help trying in my poor way to be an ambassador for Him with you. I do not like that any of you should live at enmity with my Father who made you; and that you should be wantonly provoking Him by preferring evil to good. Why should you not be at peace with the One who so much wants to be at peace with you? Why should you not love the God of love, and delight in Him who is so kind to you? What He has done for me He is quite willing to do for you: He is a God ready to pardon. I never knew a single case of a man who trusted Jesus, and asked to be forgiven, confessing his sin and forsaking it, who was cast out. ~ C.H. Spurgeon
