I don't think it is just coincidence that our life as believer's is also called our walk. I can imagine how often God has also done much of the same for us as we have grown. He holds us up, guides us, we fall, He picks us up. And the goal is a little different in that we learn instead to be more dependent on Him, rather than on ourselves - but I would like to look at two important aspects of our walk.
2 Corinthians 5:7
For we walk by faith, not by sight
In this verse we see the obvious connection to our eyes, and the truth that we press forward either without seeing what may be ahead, or we do see; but what may try to discourage us does not hinder us. But with the idea of walking, let us think on the fact that our foundation is faith.
And also:Ephesians 6:15
And your feet shod with the preparation of the gospel of peace;
As we walk by faith, we walk with the purpose of the Gospel. One foot in front of the other - we learn to walk.
