Then and only then will you become a channel of God's love to other people. God has no favorites in His body. Simon was as equally blood bought and washed as were the others, including Peter. Just as Simon didn't know, many saints in Paul's day didn't know about the power they already have in Christ. And it is the same today.
Countless saints are completely ignorant of the fact that they already have power.
Power over the law, power over sin, and power in service. All too often we hear of individuals saying that to attend such and such a church will change your life and give you the power. Power received after conversion is to be rejected. It is not the power of God, but rather the soul and potentially Satan. Real evidence of genuine power is the release of what God has already given you in Christ.
