Rearward takes recollection, the status quo sight, but,"forward:" demands the vision of faith. It is uncharted, scary, intimidating, yea seemingly impossible; but forward is exactly where GOD is leading. Oh the bliss of a tight spot; for where else can GOD be GOD? Let the 'also rans' of the faithless plod around in their ingenuity; but HIS Word is clear that: "The just shall live by his faith..." Forward is the only direction GOD knows; and your lean there is not commanded that HE may be proven, but that you may be! If faith fails at your Red Sea, it becomes your Dead Sea instead, at least for all the impractical purposes of your religion. GOD'S ways have never been, nor will they ever be ours (cf. Isaiah 55:8-9). If your back is against the proverbial wall, and the dust of the manslayer who pursues you gathers in your sight; there is no time for shipbuilding. When HE says: "go", don't go back; but rather look to the other shore and leave the means to get there in HIS capable and omnipotent hands.
Left to ourselves we would abide on our little beach front, basking in the self-righteousness of half obedience. GOD, knowing this well, sends the charioteers of crisis our way to move us on in HIS will and promise. The Apostle Paul, recounting the Exodus to Corinth centuries later writes: "Moreover, brethren, I would not that ye should be ignorant, how that all our fathers were under the cloud, and all passed through the sea; And were all baptized unto Moses in the cloud and in the sea; And did all eat the same spiritual meat; And did all drink the same spiritual drink: for they drank of that spiritual ROCK that followed them: and that ROCK was CHRIST." In regard to whatever, or whomever, is impeding your Christian inertia, GOD commands: "go forward:"
Do you find yourself between a ROCK and a Red Sea? If so, lift your faith toward Heaven and go forward, cross over on the ROCK.
"Sing ye to the LORD, for HE hath triumphed gloriously; the horse and his rider hath HE thrown into the sea."
