aha moment

I had an aha moment last night. I've been reading abit about meditation, its benefits, ways of doing it etc. but I was still struggling with it. For one, sitting still long enough to actually meditate is huge already...as any parent knows, theres always SOMETHING you could be doing. Also, I have a church background and while I know people do meditate in that faith, it still seemed mystical and I would hit a block in myself. Am I really ok to be doing this? I've also been struggling with when I work out, always so tired lately. Then driving home from kungfu last night a song based on a bible verse I learned as a child came to me
'they that wait upon the Lord shall renew their strength; they shall mount up with wings as eagles. They shall run and not be weary, they shall walk and not faint. Teach me Lord, to wait. Teach me to wait, down on my knees till in your own good time you answer my pleas. Teach me not to rely on what others do, but wait in prayer for an answer from you.'
Waiting. Sitting in prayer/meditation. Strength. Endurance. Answers
I think I know what I need now.
