'Upright' in the Bible

But it is from Him that you are in Christ Jesus, who became to us wisdom from God [revealing His plan of salvation], and righteousness [making us acceptable to God], and sanctification [making us holy and setting us apart for God], and redemption [providing our ransom from the penalty for sin],

Does any one of you, when he has a complaint (civil dispute) with another [believer], dare to go to law before unrighteous men (non-believers) instead of [placing the issue] before the saints (God’s people)?
