I was baptized as a L.D.S. member on January 15, 2011. I was also raised Pentecostal.
I don't know how to post to the member about faith.
What I wanted to say is this .
To increase your faith, first find your weakness' then whatever they are concentrate on those and pray about them and no longer have that desire.
The Holy Ghost through Jesus Christ will help you and guide. The more you smile and feel good about yourself you will find a change in your life and through that change your faith will grow.
With Love in Jesus Christ Amen,
