Peter said that Jesus’ miracles proved that he is the Messiah.
People of Israel, listen! God publicly endorsed Jesus the Nazarene by doing powerful miracles, wonders, and signs through him, as you well know.Acts 2:22 (NLT)
Some people discount Jesus’ miracles and relegate them to the realm of mere legend, but the people of that day knew first hand that they were genuine. In fact, Jesus boldly challenged those who doubted his identity as the Messiah to believe in him because of his miracle.
...The proof is the work I do in my Father’s name. John 10:25 (NLT)
When we share the gospel, we have the opportunity to bring people face to face with Jesus’ miracle working power, which testifies to God’s love and the truth of the gospel. We should stay alert to the Holy Spirit, who may prompt us to pray for those around us.
If we boldly pray for healing and miracles in Jesus’ name, we give the Holy Spirit a chance to demonstrate God’s love and the truth of our message.
Paul understood that God wants the gospel to be our words accompanied by a demonstration of power through the Holy Spirit.
For when we brought you the Good News, it was not only with words but also with power, for the Holy Spirit gave you full assurance that what we said was true... 1 Thessalonians 1:5 (NLT)
