Genesis 15:1-12, 17-18
It is a primal story, an odd story, our story. Paul names it as a taproot gospel story. It is the story of Abraham. He and aging wife Sara have left home and family, risking everything on God. Still there is no child, no home, no sign of the future God has promised. Now the LORD appears in a vision:
“Do not be afraid, Abraham, I am your shield; your reward shall be very great.” Abraham is the great-great grand-father of the faith. Abraham is the primal figure of faithfulness. When God promises Abraham safety and a future we expect Abraham to say “Yes, Lord”. But, no. Abraham questions God’s integrity:
“O LORD God, what will you give me, for I continue childless … You have given me no offspring, and so a slave born in my house is to be my heir.” Abraham puts God on the witness stand and pokes holes in God’s testimony. “Oh, really”, says Abraham, “and on what basis am I to trust your promise since there is no child yet? In case you hadn’t noticed, we are not getting any younger.” We expect the story about the progenitor of the faith to portray him as confident, sure, as - well - trusting. But it does not. It makes a point of noticing that Abraham struggles to trust in God’s promise of an improbably blessed future. All the evidence suggests that Abraham and Sara are not the beginning of a new people in whom
“all the families of the earth shall be blessed” (Gen. 12:3). Everything points to them being the end of the line. Abraham and Sara are proto-types. They are proto-types for all those who follow their footsteps in the faith - in the trust - that God will birth a future out of barrenness. It turns out that it is proto-typical for believers to disbelieve.
