[Excerpt from Blackaby, Experiencing God Day by Day, September 27. Please pray for Dr. Blackaby's recovery from a recent medical problem].
. . . Casting our cares is a choice. It means consciously handing over our anxiety to Christ and allowing Him to carry the weight of our problems. At times this is the most difficult part of trusting God! We don’t like turning over the responsibility for our problems. We have been taught that self-reliance is good and praiseworthy. We may even enjoy worrying. Yet if we are to be freed from the burden of our concerns, we must choose to cast them into the strong hands of our Father.
Peter does not distinguish between little cares and big cares. God does not differentiate between problems we should handle on our own and God-sized needs. He asks us to turn them all over to Him. One of our greatest errors is to assume we can deal with something ourselves, only to discover that we really can’t.
God sees you as His frail child, burdened with a load that surpasses your strength. He stands prepared to take your load and to carry it for you. Will you let Him?
