'Powerful' in the Bible

The Son is the radiance of God’s glory and the exact expression of His nature, sustaining all things by His powerful word. After making purification for sins, He sat down at the right hand of the Majesty on high.

For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.

in order that through two unchangeable things, in which [it is] impossible for God to lie, we who have taken refuge may have powerful encouragement to hold fast to the hope set before [us],

put out raging fires, escaped death by the sword, found strength in weakness, became powerful in battle, and routed foreign armies.
