Only Spirit-guided wisdom makes the Word effective in the problem solving area. The prime cause of problems is solutions. Often, we fail to see the potential in our difficulties. The apostle's defenseless response demonstrate the potential they saw in the problem. It was an opportunity for the Spirit's teaching to become practical in a real life experience.
Wisdom is discovered through the problems encountered.
It was a golden opportunity for the Spirit to manifest God's power and wisdom to overcome the barriers erected by Satan. Every problem is an opportunity to prove God's power. Every day we encounter countless golden opportunities, brilliantly disguised as insurmountable problems. It may not seem like it at first, but there is a way out. So the word of God spread.
