It wasn't more than a few months ago that I helped my 1 year old learn to walk. Every night I would take both of his little hands and take laps around the house. He would struggle to put one front in front of the other, I would often have to help him lean into it. As time went by though he learned. However, he didn't learn by me always holding his hands. At times I would let go of one or both - that is how he learned. While he was devastated when it appeared that I had abandoned him, I knew I was right there, ready to grab him again if needed. I would let him struggle, but I would never let him fall.
Our Father in Heaven is often like that. We at times feel like he has let go, but He is right there, He will never let us fall.
The Lord makes firm the steps
of the one who delights in him;
though he may stumble, he will not fall,
for the Lord upholds him with his hand
