Acts 9:39 Then Peter arose and went with them. When he had come, they brought him to the upper room. And all the widows stood by him weeping, showing the tunics and garments which Dorcas had made while she was with them.
If a bunch of people called you up and begged you to come and bring a dead person back to life, what would you do?
Peter had the faith to trust God and allow God to bring Tabitha back from the dead. He did not trust in himself but in Christ.
We need to trust in Christ totally before we will see huge changes in others; if we show them doubt, doubt is what they will see.
Show people your faith and belief in Christ your King!
