The world prefers that we do not confess when we disobey God. For that matter, the world prefers when we do not obey God. It might seem as if this puts us in a position where we cannot win. By faith we know that it means we are.
Noah showed how this works.
By faith Noah, being warned by God concerning events as yet unseen, in reverent fear constructed an ark for the saving of his household. By this he condemned the world and became an heir of the righteousness that comes by faith. (Hebrews 11:7)
Noah believed God and did all that God commanded him, and look what it accomplished: “by this he condemned the world.” His obedience to build a boat–not his letters to the editor, his weekly sermon podcast, or his public revival meetings–declared the disobedience of the world. Noah trusted and submitted to God and, because his generation saw him do it, they were accountable for it. They couldn’t say that they didn’t know.
They were responsible for 100 years of mockery-of-mouth toward the ark-itect, 100 years of laughing off the ridiculous idea of rain, 100 years of evidence they couldn’t un-see.
Just because our obedience isn’t as dramatic doesn’t mean that it isn’t as effective in condemning the world. Even when we disobey but then acknowledge our sin and seek God’s forgiveness in Christ, we show the world what they should do. By faith we trust the judgment of God on His Son, by faith we expect the judgment of God by His Son, and by faith we become the heirs of righteousness. Our obedience of faith is antithetical worship and a witness to the unbelieving culture.
