“While we look not at the things which are seen, but at the things which are not seen: for the things which are seen are temporal; but the things which are not seen are eternal” (2 Corinthians 4:18).
In the prophetic program (past or future), God forms a bloodline of a literal, physical, visible, earthly people—the nation Israel. Accordingly, He demands they perform literal, physical, visible, earthly works—physical circumcision, water baptism, tithing, Sabbath-Day observance, confession of sins, and so on. Moreover, He promises them literal, physical, visible, earthly demonstrations of His power—healed bodies, bountiful harvests, military victories, et cetera (signs, miracles, and wonders).
However, in the mystery program, our present-day, God is forming a spiritual, invisible, heavenly people—although just as real as Israel. The Bible calls it “the Church the Body of Christ,” people “blessed with all spiritual blessings in heavenly places in Christ” (Ephesians 1:3). In our Dispensation of Grace, Father God is not forming a literal, physical, visible group of believers. Therefore, we are not looking for literal, physical, visible, earthly works of God. We are to be looking, with the eyes of faith, at the invisible, spiritual works of God (today’s Scripture; 2 Corinthians 5:1). One of these invisible, spiritual blessings is a glorified body, “eternal in the heavens.”
Ironically, those who would have us walk by sight when Scripture instructs us to walk by faith are actually emboldening doubt rather than faith. We do not have to see God visibly working to know He is with us. Rather, we know He is with us because His Word says His Holy Spirit is working in us to produce Christ’s life: “That [Father God] would grant you, according to the riches of his glory, to be strengthened with might by his Spirit in the inner man, that Christ may dwell in your hearts by faith…” (Ephesians 3:16,17). source
