How do we know that Philip was sent by God?

We know Philip was sent by God because the angel of the Lord spoke to him, directing him to meet the Ethiopian eunuch (Acts 8:26). His obedience to the Holy Spirit's command to approach the eunuch shows his faithfulness as a servant of the Lord. Moreover, his actions exemplify the response of a faithful minister, as he opened his mouth and preached Jesus. Just as John the Baptist was sent from God to bear witness of the light (John 1:7), Philip was also sent as a witness to God’s grace and redemptive plan in Christ. This pattern illustrates how God actively directs his servants to fulfill His purposes in the lives of the lost.
