Interesting quote from Charles Spurgeon:
Now, wherever you read of the God of Jacob in the Bible, you should remember the covenant with Jacob. Christians love to think of God's covenant. All the power, all the grace, all the blessings, all the mercies, all the comforts, all the things we have, flow to us from the well-head, through the covenant. If there were no covenant, then we should fail indeed; for all grace proceeds from it, as light and heat from the sun. No angels ascend or descend, save upon that ladder which Jacob saw, at the top of which stood a covenant God. Christian, it may be that the archers have sorely grieved you, and shot at you, and wounded you, but still your bow abides in strength; be sure, then, to ascribe all the glory to Jacob's God.
