One definition of gate is a moveable barrier, usually on hinges, closing an opening in a fence, wall or enclosure.  Today we added a substantial gate to our deck. As long as we have had a dog we could prop up a baby fence at the top of the stairs. But we now have a mobile grandchild and nieces and decided we needed a safer option.
I let the dogs onto the deck and they ran right to it and barked. They may think of it is a barrier to their freedom when it is for their own safety.
I'll try to remember the next time God puts a barrier in my path, that it is for my own protection.
Psalm 143:8
Cause me to hear Your lovingkindness in the morning, for in You do I trust; cause me to know the way in which I should walk, for I lift up my soul to you.

This is the view from the top of my stairs.
