Ultimately, however, it is God Himself we are to stand on, to cling to.
Recently the Lord gave me a book by Oswald Chambers called If Ye Shall Ask... (the original 1938 edition of If You Will Ask: Reflections on the Power of Prayer). I've been reading it most mornings before prayer. The passage below is from chapter 10:
"...the mistake is putting an abstract truth deduced from God in the place of God Himself. Abraham had none of the fanatical in him, he did not stand true to what God said, but to God Who said it. God said, 'Offer up Isaac,' and then God said, 'Don't.' A fanatic would have said, 'I will stick to what God has said, this other voice is of the devil.' Watch when some providence of God is going against what we have asserted God will always do."
Stand on God Himself, not on abstract principles. Don't try to predict how God will answer, according to what you've learned about what God "always does." Even Scripture can only give sweet glimpses of who God is. Just as a love letter makes us long to draw close to our sweetheart, Scripture's purpose is to set us on a deep quest to know the Writer Himself.
His promises form parts of His signature. Cling tightly to the hands that wrote them, and be drawn to His heart.
