'Strength' in the Bible

Having ever in mind your work of faith and acts of love and the strength of your hope in our Lord Jesus Christ, before our God and Father;

but after we had already suffered and been outrageously treated in Philippi, as you know, yet in [the strength of] our God we summoned the courage to proclaim boldly to you the good news of God [regarding salvation] amid great opposition.

We sent Timothy, our brother and God's servant in the good news of Christ, to give you strength and comfort in your faith;

And our desire is that you will keep control over those whose lives are not well ordered, giving comfort to the feeble-hearted, supporting those with little strength, and putting up with much from all.
