Apparently this was an actual "hike" and not merely a stroll through the woods as there was some elevation and rock climbing involved (now that could just be Robbie as well, never met a rock he didn't want to climb).
In this picture you can see that Robbie has found a foothold that gave him a place to leverage his weight so that he could scale this smooth rock. It was just what he needed.
What footholds does God provide for us?
You have to look for footholds when you're climbing but they're usually there. We know we won't be tempted above that which we are able - and let's broaden our typical understanding of "tempted" - not only temptation as in to do wrong but also tempted to not do what we should...in other words - we are tempted to not trust God in a situation, tempted to despair or give up.
"No temptation has overtaken you except such as is common to man; but God is faithful, who will not allow you to be tempted beyond what you are able, but with the temptation will also make the way of escape, that you may be able to bear it" I Corinthians 10:13 I think that means He will provide a foothold - God's way of making a way when there seems to be no other way.
Are we willing to put our faith securely in that truth and push off from there -grasping for what seems so high above our own abilities?
