Then the high priest and all his associates, who were members of the party of the Sadducees, were filled with jealousy. (Acts 5:17)
The apostles of Christ did the work of the Father and the miracles took place, since their work stood out making all the difference. Thus, they reached success and bothered hell and the devils servants.
Usually when a person begins to give fruits in his or her work, someone who would like to be in their place begins to persecute them and create situations to harm them. That is exactly what happened to the apostles. They were put in jail (Acts 5:18), however, the Lord sent His angel and delivered them.
If someone is jealous of you, do not fear, for God is by your side. This also shows that you are a conqueror, since no one is jealous of a loser.
Peace be with you.
