Consider Isaac — the man in the middle. Those who study the life of Isaac must untangle his story from the events of his more famous father and from the history of his more famous son. He actually lived longer than Abraham or Jacob, but his 180 years are almost invisible unless one makes a deliberate search to disentangle his story.
Isaac represents the average believer, the man in the middle who does not have the great faith attributed to Abraham. They are ever crying Mark 9:20: “I believe, help my unbelief.” Just so, the one in the middle cannot claim the dramatic testimony of Jacob. Not every Christian can claim that they have been ambushed and wrestled by the Lord Jesus and dramatically transformed in a single night. It is a sad fact that some uninstructed Christians actually express a disappointment that they cannot boast a dramatic testimony.
Yet, God is the God of Isaac as well as the God of Abraham and Jacob. Isaac cannot claim to be a great man of faith as his father, or one who was notably converted as his son, yet Isaac had a wonderful contribution to make in the history of redemption. Isaac was a link — a redemptive link. If you asked Isaac to mention some accomplishment he made for the Lord in his 180 years, he would be hard-pressed to nail something down. He didn’t start a ministry; he never wrote a book; he didn’t play a harp or other musical instrument; he couldn’t use a sling. But God placed Isaac in the middle as an important link to all that came before and to all that would follow. If it were not for Isaac, there would not have been a Jacob. When you sing the wonderful Psalms of David, thank God for Isaac, for without him the sweet psalmist of Israel would not have existed. The reality is: Isaac was the promised seed that pictured the Lord Jesus as the Promised Seed. In God’s wisdom, Isaac was a link to Bethlehem and to Christ Himself.
Let us not forget to thank the Lord for the many links that He has brought into our lives. Do you remember the name of that teacher, that coach, that neighbor who guided you along the way? The link is the one who ministers by smiling, nodding in sympathy, squeezes the hand and privately slips you the Lord’s provision. They are hidden, for a short while, behind the curtain, and often do not even realize that God is using them to quietly bring Christ into the world. The God of Abraham and the God of Jacob is also the God of Isaac. We celebrate the many links that provide strength for the chain.
