I promised myself a long time ago I would work on vocalizing my testimonies during church service on Sundays. This is a personal decision. My salvation is not contingent upon it. Scripture tells us the only thing we must do to be saved is believe (Grace through faith).
Once we are saved we begin to transform. Some experience immediate, significant changes. Drug abusers and alcoholics may walk away from the addictive substance and never use them again. Some believers receive immediate healings. The experiences are unique to the individual.
Other believers are slowly transformed. Changes for some take place one thing at a time. The new believer may begin placing a one dollar bill in the offering plate. Over time, the believer notices they have more to offer. Before long they are able to provide a significant amount to the continuation of God’s work.
Christ’s great commission (Matthew 28:16-20) to the church (believers, not a particular denomination or building) was to “(19) …go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, (20) and teaching them to obey everything I have commanded you.”
I believe part of “teaching them” includes sharing our testimony. In other words, teach by sharing. If my testimony can help another get past the idea that The Lord would not accept someone like them, then I need to share it.
Sharing our individual testimonies not only blesses and teaches others, it is a form of praise to The Lord and witness of His greatness and love.
