Why Has God Become Flesh to Perform His Work in the Last Days?
The brother went on, saying, “So then, why does the Lord have to appear and work in the flesh when He returns in the last days, and not appear and work directly in the resurrected spiritual body? In the Age of Grace, the Lord Jesus performed the work of redemption. Though our sins have been forgiven, our sinful nature remains deeply rooted within us, we are filled with such satanic dispositions as arrogance and conceit, selfishness and meanness and wickedness and deceitfulness, and we are still capable of involuntarily sinning and resisting God. If this carries on, then we will never be made clean, and we will be simply unworthy to enter into the heavenly kingdom.
