2Co 1:24 Not for that we have dominion over your faith, but are helpers of your joy: for by faith ye stand.
It is a tremendous ministry pastors, teachers, evangelists, and good brothers and sister have for believers who need encouragement in the faith and growth in the Lord.
Iron sharpens iron. These friends in the family of the Lord tend to stretch our faith to match to situations we face. Sometimes that stretching is a bit painful, but oh so needful.
How many times have others cared enough about me to help me along in the faith? They were patient enough to disciple me. They would either overlook the rough edges or have the boldness to help chip them away. They were my helpers in the faith in the areas of music, witnessing, Bible study, preaching, teaching, counseling, etc.
Everybody needs a helper in the faith. If you are a mature believer, there are plenty of newbies who need a spiritual mentor. If you are a babe in Christ, ask your pastor or the one who led you to the Lord to assign you someone who could be your helper in the faith.
