Every child learns to walk by falling down countless times.
I don't know of any parent who tells their child, after they fall: "Sorry honey, walking just isn't for you!"
Likewise, after a child falls down, they don't think to themselves: "maybe walking isn't for me."
Instead, they get up and instinctively try again. Eventually, they learn to walk.
Your Christian walk is much the same. You will fall down and it will hurt. There will be set-backs that will upset you. It doesn't mean that walking isn't for you.
Now GET UP and try again!
Psalm 37:23-24 The steps of a good man are ordered by the LORD: and he delighteth in his way. Though he fall, he shall not be utterly cast down: for the LORD upholdeth him with his hand.
