Psalm 139:14 I will praise You, for I am fearfully and wonderfully made; Marvellous are Your works, And that my soul knows very well.
One of the things I found as a youngster was knowing there must be something or someone out there who is in control of things because nobody around me seemed to see the big picture and know enough.
Somehow we know there is a God even before we get to know Him. We know we have something to look forward to even before we get to know Him.
When we do get to know Christ we then begin to understand how much He loves us through seeing how much He is responsible for in our lives.
