“boasting about your own pretentious plans…is evil.” -James 4:16
Having confidence is wonderful, when it is connected to confidence we have through faith given by God.
Paul wrote of, “Christ Jesus our Lord, in whom we have boldness and access with confidence through our faith in him.” Ephesians 3:11-12
Paul also wrote that when it comes to boasting…"And because of him you are in Christ Jesus, who became to us wisdom from God, righteousness and sanctification and redemption, so that, as it is written, ‘Let the one who boasts, boast in the Lord.’” 1 Corinthians 1:30-31
But confidence solely in ourselves and boasting of our own efforts are foolish.
Look at those of other religions who “attempt” through self-confidence and their own efforts to bring themselves close to God, but are faced with the truth that “all have sinned and fall short of the glory of God” Romans 3:23. We could never make it to God on our own and by our own self-confidence, we needed and still need Jesus to be that bridge to God. God sent Himself to save us. That work was 100% His part.
Jesus is our confidence!
