'Approved' in the Bible

He made Christ who knew no sin to [judicially] be sin on our behalf, so that in Him we would become the righteousness of God [that is, we would be made acceptable to Him and placed in a right relationship with Him by His gracious lovingkindness].

For it is not he who commends and praises himself who is approved [by God], but it is the one whom the Lord commends and praises.

But I pray to God that you may do nothing wrong. Not so that we [and our teaching] may appear to be approved, but that you may continue doing what is right, even though we [by comparison] may seem to have failed.
