I will go before thee, and make the crooked places straight: I will break in pieces the gates of brass, and cut in sunder the bars of iron. -Isaiah 45:2
This was for Cyrus; but it is evermore the heritage of all the Lord’s own spiritual servants. Only let us go forward by faith, and our way will be cleared for us. Crooks and turns of human craft and satanic subtlety shall be straightened for us; we shall not need to track their devious windings. The gates of brass shall be broken, and the iron bars which fastened them shall be cut asunder. We shall not need the battering ram nor the crowbar: the Lord Himself will do the impossible for us, and the unexpected shall be a fact.
Let us not sit down in coward fear. Let us press onward in the path of duty, for the Lord hath said it: “I will go before thee.” Ours not to reason why; ours but to dare and dash forward. It is the Lord’s work, and He will enable us to do it: all impediments must yield before Him. Hath He not said, “I will break in pieces the gates of brass”! What can hinder His purpose or balk His decrees? Those who serve God have infinite resources. The way is clear to faith though barred to human strength. When Jehovah says, “I will,” as He does twice in this promise, we dare not doubt.
