The Greek verb dynateō means to be strong or mighty, to demonstrate power and capability. Related to dynamis (power) and dynatos (powerful, able), it emphasizes the active exercise of divine capability. In the New Testament it appears in 2 Corinthians 9:8 and 13:3.
In 2 Corinthians 9:8, Paul declares that 'God is able (dynateō) to make all grace abound to you' — expressing confidence in God's inexhaustible power to provide for every good work. In 2 Corinthians 13:3, Paul speaks of Christ who 'is not weak in dealing with you, but is powerful (dynateō) among you.' The verb anchors the believer's confidence not in human ability but in the active, present power of God.
