God seems to use us to do His miracles at just the right time to get the job done. Be available. You may not be able to heal the sick but a word you speak inspired by the Holy Spirit may be just the right one to save someone.

Acts 19:11-12

And God was doing extraordinary miracles by the hands of Paul, so that even handkerchiefs or aprons that had touched his skin were carried away to the sick, and their diseases left them and the evil spirits came out of them.
