Repent ye therefore, and be converted, that your sins may be blotted out, when the times of refreshing shall come from the presence of the Lord… – Acts 3:19
Jesus is yet to come a second time, and like a mighty shower flooding a desert shall His coming be. His church shall revive and be refreshed; she shall once again lift up her head from her lethargy, and her body from her sepulchre. But woe unto you who are not saved when Christ cometh, for the day of the Lord will be darkness and not light to you. When Christ cometh to the unconverted, “the day shall burn as an oven; and all the proud, yea, and all that do wickedly, shall be stubble.” “But who may abide the day of His coming? and who shall stand when He appeareth? for He is like a refiner’s fire, and like fullers’ soap: and He shall sit as a refiner and purifier of silver: and He shall purify the sons of Levi.” Oh, if ye repent and be converted, ye shall stand fully absolved in the day of His coming, when heaven and earth do reel, when the solid rock begins to melt, and the stars, like fig-leaves withered, fall from the tree, when the trumpet sounds exceeding loud and long, “Awake, ye dead and come to judgment,” when the grand assize is sitting, and the Judge shall be there-the Judge of the quick and dead, to separate the righteous from the wicked. The Lord have mercy upon you in that day; and so He shall if His grace shall make you obedient to the words of our text, “Repent and be converted, that your sins may be blotted out, when times of refreshing shall come from the presence of the Lord.” ~ C.H.
