Sergius Paulus wanted to hear the Word of God. So he called for Paul and Barnabas to come to preach to him. 
When the preachers arrived Elymas, a false prophet who was with Sergius, tried to stop Barnabas and Paul from getting to Sergius. He knew that these men spoke truth and he wanted Sergius to have no part in it. 
Are you under the impression that no one really intends to hurt you? That everyone is looking out for your best interest?

Don’t be deceived.
The battle we are in is real. Be careful who you surround yourself with. Who you allow to have influence over you.
