I Samuel 2:9

Then said David to the Philistine, Thou comest to me with a sword, and with a spear, and with a shield: but I come to thee in the name of the Lord of hosts, the God of the armies of Israel, whom thou hast defied.

And David put his hand in his bag, and took thence a stone, and slang it. So David prevailed over the Philistine with a sling and with a stone.

The way is slippery and our feet are feeble, but the Lord will keep our feet. If we give ourselves up by obedient faith to be His holy ones, He will Himself be our guardian. Not only will He charge His angels to keep us, but He Himself will preserve our goings.

He will keep our feet from falling so that we do not defile our garments, wound our souls, and cause the enemy to blaspheme.

By faith Moses. . . . chose.” Faith rests on promise; to faith, the promise is equivalent to fulfillment; and if only we have the one, we may dare to count on the other as already ours. It matters comparatively little that the thing promised is not given; it is sure and certain because God has pledged His word for it, and in anticipation we may enter on its enjoyment. Had Moses simply acted on what he saw, he would never have left Pharaoh’s palace.

But his faith told him of things hidden from his contemporaries, and these led him to act in a way which to them was perfectly incomprehensible.

If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth: but if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin.—He that is washed needeth not save to wash his feet, but is clean every whit.

I have taught thee in the way of wisdom; I have led thee in right paths. When thou goest, thy steps shall not be straitened; and when thou runnest, thou shalt not stumble. Enter not into the path of the wicked, and go not in the way of evil men. Avoid it, pass not by it, turn from it, and pass away. Let thine eyes look right on, and let thine eyelids look straight before thee. Ponder the path of thy feet, and let all thy ways be established. Turn not to the right hand nor to the left: remove thy foot from evil.
