Flesh and blood do not here signify sin, the unrenewed nature, (as some would have it), but our bodies, in their present natural, corruptible, frail, mortal state; so the terms signify, Ephesians 6:12 Hebrews 2:14. Flesh and blood shall inherit the kingdom of God, (else our bodies could not be glorified), but our body, as in its present state, till changed and altered as to qualities, till it be made a spiritual body, shall not inherit the kingdom of God. The latter words give a reason why flesh and blood cannot inherit the kingdom of God; because it is corruption, that is, subject to natural corruption and putrefaction, and the heavenly state of incorruption; the bodies of believers therefore must be raised up in that state of incorruption mentioned 1 Corinthians 15:42, before they can be capable of inheriting the kingdom of God.
