believing and saying

One believes with the heart, resulting in righteousness, and one confesses with the mouth, resulting in salvation.

Romans 10:10 HCSB

Believing impacts the depth of who we are.  It is not a cursory event, but rather a life changing ongoing process. My beliefs are evident in my life. If I believe Jesus is my saviour, I will act like it rather than behave as if I am my own saviour.

Confession also is an ongoing process. Whilst I might initially come to Christ and confess Him as saviour,  I show Him as Lord by the ongoing confessions of my mouth.

So, both believing and confession are ongoing and life changing processes. Amen!
