'Merely' in the Bible

For our reason for boasting is this: the testimony of our conscience that we conducted ourselves in the world, and especially toward you, in holiness and purity of motive from God, not in merely human wisdom, but by the grace of God.

For we do not preach ourselves, but rather Jesus the Messiah as Lord, and ourselves as merely your servants for Jesus' sake.

Not only [did they give materially] as we had hoped, but first they gave themselves to the Lord and to us [as His representatives] by the will of God [disregarding their personal interests and giving as much as they possibly could].

for the weapons of our warfare [are] not merely human, but powerful to God for the tearing down of fortresses, tearing down arguments

Since many boast for merely human reasons, I too will boast.
