Wood wrote, "The evidence that spiritual renewal, or regeneration, was true of such Old Testament people lies mainly in two directions.
"[1] According to Wood, the Scripture stated that the Holy Spirit God is omnipresent and necessary in the current age prior to the Church's Rapture and the Great Tribulation, for imparting a new life "to those who trust Christ as their Saviour".
[2] His action mainly differs from the past in that the Holy Spirit "will cease one aspect of His work, namely, the restraint of sin in the world" (2Thess 2:7).
Wood was educated at Calvin Theological Seminary with graduate studies in Israel through New York University and at the Oriental Institute, Chicago.
[6] Wood is best known for his advocacy and promotion of the controversial "gap theory" of Creation Science and his spirited defence of the plenary inspiration of Scripture.
