'Ability' in the Bible

But you will receive power and ability when the Holy Spirit comes upon you; and you will be My witnesses [to tell people about Me] both in Jerusalem and in all Judea, and Samaria, and even to the ends of the earth.”

And with great ability and power the apostles were continuously testifying to the resurrection of the Lord Jesus, and great grace [God’s remarkable lovingkindness and favor and goodwill] rested richly upon them all.

Now Stephen, full of grace (divine blessing, favor) and power, was doing great wonders and signs (attesting miracles) among the people.

how God anointed Jesus of Nazareth with the Holy Spirit and with great power; and He went around doing good and healing all who were oppressed by the devil, because God was with Him.

So the disciples decided to send a contribution, each according to his individual ability, to the believers who lived in Judea.
