'Approved by God' in the Bible

Instead, we speak as men approved by God to be entrusted with the Gospel. So, we speak, not trying to please people but God, who examines [the motives of] our hearts.

Do your best to present yourself as a worker who is approved by God [and] does not have to be ashamed, [because you are] accurately handling [i.e., explaining] the message of truth.

The person who perseveres under trials is blessed, because when he has been approved by God, he will receive the crown of [never ending] life, which God has promised to those who love Him.
