At the New York Conference Mr. Hudson Taylor-spoke of the source of power for Christian missions, and gave an instance of what the power of believing prayer is. I quote at some length from his speech—
“God Himself is the great source of power. Power belongeth unto God.…
Further, God’s power is available power. We are a supernatural people, born again by a supernatural birth, kept by a supernatural power, sustained on supernatural food, taught by a supernatural Teacher from a supernatural book. We are led by a supernatural Captain in right paths to assured victories.
The risen Saviour, ere He ascended on high, said to His disciples, ‘Ye shall receive power when the Holy Ghost is come upon you.’ Not many days after this, in answer to united and continued prayer, the Holy Ghost did come upon them, and they were all filled. Praise God, He remains with us still.
The power given is not a gift from the Holy Ghost. He Himself is the power. To-day He is as truly available and as mighty in power as He was on the day of Pentecost. But has the whole Church ever, since the days before Pentecost, put aside every other work and waited for Him for ten days, that that power might be manifested? Has there not been a source of failure here?
We have given too much attention to methods and to machinery and to resources, and too little to the Source of Power—the filling with the Holy Ghost. This, I think, you will agree with me, is the great weakness, has been the great weakness, of our service in the past, and, unless remedied, will be the great weakness in the future.
We are commanded to be filled with the Spirit. If we are not filled, we are living in disobedience and sin, and the cause of our sin is the cause of Israel’s sin of old—the sin of unbelief.
