'Able' in the Bible

He comforts us in all our affliction, so that we may be able to comfort those who are in any kind of affliction, through the comfort we ourselves receive from God.

Now if the ministry of death, chiseled in letters on stones, came with glory, so that the Israelites were not able to look directly at Moses’ face because of the glory from his face—a fading glory—

And God is able to make every grace overflow to you, so that in every way, always having everything you need, you may excel in every good work.

For we are not able to do anything against the truth, but only for the truth.
