He hath blessed, and I cannot reverse it.
BALAAM would have reversed the blessing into a curse, had he been able. Large rewards were depending on his doing so. But he was restrained. The current of blessing was running too strong for him to stem: the music was too overpowering for him to alter the air. Is not this also the despair of Satan? God hath blessed us with all spiritual blessings in Christ Jesus, and he cannot reverse them.
The blessing of adoption.—When the soul believes in Jesus, it is adopted into the family of God; the new life begins to throb within; it is constituted an heir of God, a joint-heir with Christ (John 1:12). This position is irreversible. We may be tempted and overthrown, we may go for a season into the far country, we may even bring the family-name into contempt; but Satan cannot untie the knot with which God has bound us to Himself.
The blessing of acceptance in the Beloved.—We are in Him, chosen in Him before the foundation of the world, risen and ascended and seated in Him in the heavenlies; and as our God views us in Jesus, He cannot behold iniquity or see perverseness in Him, and He accepts and blesses us as His well-beloved. This, too, is irreversible by the arts and machinations of the great Accuser.
The blessing of the covenant.—God has taken us to be a people for His own possession. His name is named on us, His character is implicated in our ultimate deliverance from evil, and glorification. If we could be cast away, He would suffer irreparable dishonor. Therefore, though Satan do his utmost to discredit us, as he did the patriarch Job, he cannot reverse the covenant in which God and we are forever and indissolubly joined.
