Acts 1:8 – But you will receive power when the Holy Spirit has come upon you, and you will be my witnesses in Jerusalem and in all Judea and Samaria, and to the end of the earth.
I think the baptism in the Holy Spirit is hugely underestimated and underemphasized in much of the church today. A sincere search of the scriptures would come to a different conclusion when estimating the value of this incredible experience. Jesus said that this baptism would be the very source of power for world evangelism and signs and wonders. He warned the disciples not to leave Jerusalem without it. I wonder how many are ignoring these instructions in our casual Christian culture. Here is an interesting testimony from the Evangelist Charles Finney describing the secret to the power in his ministry.
“But as I turned and was about to take a seat by the fire, I received a mighty baptism of the Holy Ghost. Without any expectation of it, without ever having the thought in my mind that there was any such thing for me, without my recollection that I had ever heard the thing mentioned by any person in the world, the Holy Ghost descended on me in a manner that seemed to go through me, body and soul. I could feel the impression, like a wave of electricity, going through and through me. Indeed it seemed to come in waves and waves of liquid love; for I could not express it in any other way. It seemed like the very breath of God. I can recollect distinctly that it seemed to fan me, like immense wings.
No words can express the wonderful love that was shed abroad in my heart. I wept aloud with joy and love; and I do not know but I should say, I literally bellowed out the unutterable gushings of my heart. The waves came over me, and over me, one after the other, until I recollect I cried out, “I shall die if these waves continue to pass over me.” I said, “Lord, I cannot bear any more”; yet I had no fear of death.”
Finney was a major leader in revival and evangelism in America in the early 1800’s. His meetings were characterized by the power of God that brought repentance everywhere Finney preached. Maybe this is what is missing in many churches today.
