Leon James Wood (1918–1977) was an American theologian. He is the author of one of the few books on the Holy Spirit as portrayed in the Old Testament as opposed to the New Testament. Wood wrote, "The evidence that spiritual renewal, or regeneration, was true of such Old Testament people lies mainly in two directions. One is that these people lived in a way possible only for those who had experienced regeneration, and the other is the avenue of logical deduction that argues back from New Testament truth."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". 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). Source: Wikipedia (en)
