Many people are baffled by what Jesus said to His disciples in John 14:12: “He who believes in Me, the works that I do he will do also; and greater works than these he will do.” But Jesus knew that His greatest ministry was still ahead of Him. He was going to send the Holy Spirit into the lives of believers and continue His work through them by the power of the Spirit. 

The apostle Paul said, “Now thanks be to God who always leads us in triumph in Christ, and through us diffuses the fragrance of His knowledge in every place” (2 Corinthians 2:14, emphasis added). He said, “But the Lord stood with me and strengthened me, so that the message might be preached fully through me” (2 Timothy 4:17, emphasis added).

Our Christian work is never a matter of what we are doing for Christ but of what He is doing through us by His Spirit. Those are His “greater things.” Ask the Lord to make you His channel, speaking His words and doing His works through you by the Spirit.

The only life that ever pleased God on earth was the life of Jesus Christ, and He must reproduce His life in us.
