Often times we skirt around the issue of true faith in Jesus as well as the matters of the battle in the supernatural realm.
In Acts 8 we see Simon the sorcerer seeing the full power of God and wants it for personal and selfish reasons/motives. His heart was not right and his motive was off base.
He has a non-saving faith and also a wow factor believe/amazement at the power of the Holy Spirit.
Peter boldly calls him out and challenges him to repent and follow Christ.
Trust you will find some challenges and areas to surrender and yield to the Lord. May His Word bless and keep you.
