So simple.

A friend of mine told me his favorite verses are Romans 10:8-10 ..."But what does it say? “The word is near you, in your mouth and in your heart” (that is, the word of faith that we proclaim);
9 because, if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved.
10 For with the heart one believes and is justified, and with the mouth one confesses and is saved."

...convinced, confident, sure... at my very core..... and talk about that.
So simple.
Yeah.
