'Strive' in the Bible

In fact, we labor and strive for this, because we have put our hope in the living God, who is the Savior of everyone, especially of those who believe.

But you, O man of God, must flee from these things; and strive for uprightness, godliness, good faith, love, fortitude, and a forgiving temper.

Strive earnestly in the good conflict of faith. Lay hold of eternal life, to which thou hast been called, and hast confessed the good confession before many witnesses.
