If any of you lacks wisdom, he should ask God, who gives generously to all without finding fault, and it will be given to him. God has given us the Holy Spirit for guidance. But when he, the Spirit of Truth, he will guide you into all truth. Many times the advice of a parent, pastor, youth minister, Sunday School teacher or other mature person is just what we need to hear to help us decide what God wants us to do. The way of a fool seems right to him, but a wise man listens to advice.
Plans fail for lack of counsel, but with many advisors they succeed.
The Bible says that there is a peace that comes when we are pleasing God with our lives. When deciding between two alternatives that you have been praying about, sometimes one of the options will give you a greater peace. That option is probably God's will. We should trust God in faith that He will accomplish His will in our lives. God has given each of us gifts and abilities to use in His service.
