"I have planted, Apollos watered; but God gave the increase" I Cor. 3:6. The Lord's means of preaching Christ crucified is through His sons and daughters. The Lord, not men, will going to grow His Church. However, the Lord will use men/women, boys/girls as His instruments of righteousness to accomplish His goal of saving His elect. We need to be prepared and ready at all times to witness for Christ. As we witness for Christ, we must rely upon the Holy Ghost to regenerate the lost to whom we are witnessing.
