I will say of the Lord, "He is my refuge and my fortress: My God, in Him I will trust."
Because you have made the Lord, who is my refuge, even the Most High, your dwelling place.
No evil shall befall, nor shall any plague come near your dwelling;
For He shall give His angels charge over you, to keep you in all your ways."
Psalm 91:1-2, 9-11 (NKJV)
Over the years I have done a fair amount of traveling and often I travel by airplane, which of course means going through an airport. Most airports and their bathrooms are modernized and many things are motion activated, like doors, escalators, sinks, and hand dryers. But, while these things will operate automatically there is still something that is required to activate the "automatic" function. A door will not open unless you walk towards it, the escalator will not move until you step on to it, and the water in the sink and the hand dryer will not work until you put your hands in the proper place.
We can read in the Bible about how good God is and how God provided so many things for us through Jesus. But, why is it that we don't always see these things in our everyday life? The reason is that while God has indeed provided many wonderful things for us, these things require us to do something to activate what it is that we need. Psalm 91 gives us a good example of this and shows us that by doing and saying something God is able to do what He wants to do. It does not say that just because God is so wonderful that these things happen, but they happen because of something we have done in response to what God has provided.
In Psalm 91 it talks about dwelling in the secret place of the Most High and saying that God is our refuge and fortress. Later in this same Psalm it says that because we have made Him our dwelling place and because we have made Him our refuge all these blessings of protection become ours. This is why it is so important to learn about what belongs to us as Christians and then to do our part to activate the blessings of God. For salvation, healing, protection, and provision we need to do our part to activate the blessings that God has already provided for us through Jesus, it won't just happen automatically, we have a part to play.
