Kenneth Wuest quotes:

Anxious care is out of place in a heavenly Father's presence.

Jude, a bondslave of Jesus Christ and brother of James, to those who by God the Father have been loved and are in a state of being the permanent objects of His love, and who for Jesus Christ have been guarded and are in a permanent state of being carefully watched, to those who are called ones.

The believer does not use God's power; God's power uses him.
