'Stand Firm' in the Bible

Now God is the One who makes us stand firm with you in [fellowship with] Christ. He has anointed us [Note: "Anointed" here probably refers to selecting, appointing and commissioning people for some form of Christian service. See Luke 4:18];

not that we rule [like dictators] over your faith, but rather we work with you for [the increase of] your joy; for in your faith you stand firm [in your strong conviction that Jesus of Nazareth—the Messiah—is the Son of God, through whom we obtain eternal salvation].
