The foundation of our Salvation is in our confession of Jesus as our Lord and Saviour after we have believed. Romans 10:9-10
Meditation is what influences our belief and our belief is what influences our confession.
It is necessary for you to know what God has done for you, what he has done in you, what he is doing for you and what he will do through you. This is the basis for us holding fast to the Confession of our Faith that we have believed.
Hebrews 10:23
