Sometimes, instead of referring to the two major divisions of the Bible as Old Testament and New Testament, I prefer to use First Testament and Second Testament. This helps me remember that “Old” doesn’t mean outdated, and “New” doesn’t mean forgetting what came before it.
B.B. Warfield had a great analogy. He imagined the First Testament to be a perfectly-constructed mansion. Only the finest materials had been used, and the mansion had been constructed by the best craftsmen being overseen by the world’s premier Architect. The only problem was this mansion had no lights. With the appearing of Jesus in the Second Testament, finally the lights are turned on. Jesus reveals the beauty that was already there!
In the First Testament, we frequently read that the Holy Spirit comes ON people, usually for leadership functions. We see this phrase with Moses and his co-leaders, several of the judges, Israel’s first two kings, and many of the prophets (see Numbers 11:25; Judges 3:10, 6:34, 11:29, 15:14; 1 Samuel 11:6, 16:13; 2 Kings 2:15).
However, there is one leader in the First Testament about which we notice the Spirit came IN him. Twice Ezekiel says this (2:2, 3:24). This was hinting at a to-be-fulfilled promise in the Second Testament (36:25-27).
The Holy Spirit being IN God’s people—which makes them God’s leaders—is described by Jesus in Acts 1:5. Many translations render this verse, “You will be baptized with the Holy Spirit.” But the NIV footnote and The Message both say “in the Holy Spirit.” Indeed, the Greek word means “by, with, or in.” But in context to being baptized (which means immersed, submerged, cleansed, overwhelmed), I think the best word is: baptized IN the Holy Spirit.
Let me say it again: When it comes to the Holy Spirit’s involvement in a Christian’s life: In > On.
“You hardly need to pray to have the Spirit poured out, for that has been done. What you need is a baptism of the Holy Spirit; to go down personally into that glorious flood that has been poured forth. Oh, to be immersed in the Holy Spirit and into fire—covered with His holy influence—plunged into the Godhead’s deepest sea and lost in His immensity! Here is our life and power.” —Charles Spurgeon
Jesus wants all of His followers to be baptized IN the Holy Spirit. So He told us to keep on asking, keep on seeking, keep on knocking, keep on waiting for God’s promised infilling (Luke 11:9-13; Acts 1:4-8).
Don’t stop at salvation—with just the Holy Spirit deposited in you—press on to be submerged deep into the Holy Spirit.
