We are called upon in this verse to "Behold." To look, not to ourselves or our abilities or our circumstances, but to God Himself. We are to look, not with the natural eye, for none behold God by such a look, but with the eye of faith. We are instructed by God through the prophet Isaiah to "Look unto me, and be ye saved, all the ends of the earth: for I am God and there is none else." (Isaiah 45:22).
We are not to look back at something we did, or around at something we're doing or ahead at something we plan to do. We are not to look to religion, to a church or a priest or preacher but to Him! We are to look unto God in the face of Jesus Christ, beholding the Lamb of God and we are to continue "looking unto Jesus, the Author and Finisher of our faith." Life, spiritual life, is in a look. Look to Christ who is life.
God tells us "I am the Lord." When the eternal God declares and describes Himself as the Great I am, He is saying as the old preacher said "I am was, I am is, and I am always will be!" God has always been God, always will be God and the point of great importance to us, He is God right now! The infinitely holy, majestic and almighty God.
As God He exercises a sovereign control over all things. He is the "God of all flesh." Nothing and no one is outside the realm of His total dominion and power. No devil, demon, angel or man. He is truly God over all.
Out of God's declaration of Himself flows the question, "is there anything too hard for me?" Jeremiah has already declared his doctrine in vs. 17, "Ah Lord God! Behold, thou hast made the heaven and the earth by thy great power and stretched out arm, and there is nothing too hard for thee." There are those who emphasize that "God can't save a sinner against his will." If they only knew how little a difficulty man's will is. He makes His people "willing in the day of His power." If God has not saved you it is because He has not brought you to call on Him for mercy and grace in Christ.
If He should leave you alone you will but perish. We may say with Jeremiah that nothing is too hard for God; but He must bring this truth home to our hearts. What great difficulty there is in saving such a wretched, ever-failing sinner such as I am. What a gulf to be spanned in bringing an unholy son of Adam to the Holy God. What a righteousness must be established and charged to our account before God's justice.
What a payment for our sin must be made. What a work of grace must be done in our hearts making us willing. What a continued watchcare over us is needed to present us faultless before the throne of glory.
Behold the glorious Christ standing as our Surety in the covenant, becoming a man and keeping the law on our behalf, dying in our place in the full satisfaction of divine justice, raising from the dead for our justification and seated on high at the right hand of the Majesty as our great High Priest and Intercessor. Eternally engaged as the savior of God's elect. In Christ the Savior God speaks in grace saying, "I am the Lord…nothing is too hard for me!"
Not even saving you!
