In Acts we get some insight in how Paul decides, or is led, to preach in different places.
“Paul and his companions travelled throughout the region of Phrygia and Galatia, having been kept by the Holy Spirit from preaching the word in the province of Asia. When they came to the border of Mysia, they tried to enter Bithynia, but the Spirit of Jesus would not allow them to. So they passed by Mysia and went down to Troas. During the night Paul had a vision of a man of Macedonia standing and begging him, ‘Come over to Macedonia and help us.’ After Paul had seen the vision, we got ready at once to leave for Macedonia, concluding that God had called us to preach the gospel to them.” Acts 16:6-10 NIVUK
Scripture doesn’t make it clear how the Holy Spirit prevented them from going certain places. One must assume there were circumstances, like problems at border checkpoints, that prevented them from continuing their journey. Instead of laying the blame for the lack of success on the enemy of our souls, they saw it as the Holy Spirit directing their steps.
I believe their response indicates an excellent understanding of who they are as followers of Christ: Satan has no power over them because they are walking in Christ’s victory. So no scheme of the evil one will be able to stand against them when they walk in truth with the message of Truth. The logical conclusion, when things they have planned don’t work out, is that God has other plans.
I wonder if we give our enemy undue credit at times because we have forgotten who we are as followers of Christ. Christ is victorious. Let’s live as victors, having confidence that He is directing our steps.
