The Power is with God

“But you shall receive power when the Holy Spirit has come upon you; and you shall be witnesses to Me in Jerusalem, and in all Judea and Samaria, and to the end of the earth.” -Acts 1:8

With God there is power in the ministry, power in prayer, power in all holy work. We may do a vast deal of work, and yet nothing may come of it; and, on the other hand, we may only be able to do comparatively little, and yet great results may flow therefrom: for results depend not on the quantity of the machinery, but on the presence of the Lord.

Do you not all know persons who are not peculiarly gifted, and yet are eminently useful? You do not remark anything about them that is specially noticeable, and yet their whole career enlists attention by its power. Their words tell, for there is character behind them. A consistent life gives force to a plain testimony…God Himself is at the back of the man who is living for Him. He causes him to speak in His name, so that none of His words fall to the ground. Is it not said of the godly, “His leaf also shall not wither; and whatsoever he doeth shall prosper”? This is so with every church where the Lord abides. His presence makes it a power with its children and adherents, a power with the neighborhood, and a power with the age. Its example, its testimony, its effort tells. God uses it, and therefore it answers its end. The power is with God; but the church is the instrument by which that power exercises itself. He uses a living people for the display of living power, and He gives to them both life and power, more and more abundantly. As we desire power with which to labor for God, we must pray that the God of power will remain in our midst. ~ C.H. Spurgeon
