If you say, “The Lord is my refuge,”
and you make the Most High your dwelling,
no harm will overtake you,
no disaster will come near your tent.
Psalm 91:9-10
Observation: The psalmist is making a very clear and simple promise ... if a person declares and believes that the Lord is their protector, and they then live in the Lord with the Lord himself as their home, they will indeed be protected from disaster and harm.
This is a promise that, of course, is offset against a reality, and against many other statements in scripture. Believers have suffering. David, the author of many psalms and declared by the Lord himself to be the man after God's own heart, faced hardships including attempts on his life by the king and a rebellion led by his own son. One of Jesus' best friends become so sick he died, while his sisters who clearly loved and believed in Jesus had to suffer in mourning with doubt for their future. If there were a list of those who believe in the Lord, and then a list of which of those individuals have harm and disaster in their lives ... the lists would be identical.
However, this is the promise. In that context, the issue is simple: Every believer actually fails to make the Most High their dwelling. They all declare their faith in words, but they fall short of completely and totally living their lives in a totally new and different way. That doesn't cause them to forfeit their salvation, for that comes by faith, not works. However, they cannot be totally protected from every and all earthly harm.
Application: I saw a related conversation just yesterday. It was a statement that declaring one's self to be Christian is the absolutely most difficult thing someone can do, and it is because of what Jesus says the cost of following him truly is. To believe is to suffer, face persecution, and to invite harm into your life daily.
Jesus knows the Lord's promises, so was he contradicting these promises? No. Jesus was talking, knowing the truth of mankind ... we are incapable of living a life that is totally and completely residing within the dwelling of the Lord, a life of such total devotion and life-alignment to the Lord's will that we can receive this promise.
Every day, I live outside of the Lord's will. For most Christians, we are so far removed from living within the Lord's perfect dwelling place that we can't even recognize all the ways in which we are outside of his will. I would say something like "those that are closer to living within his will, like strong pastors ..." but we've learned recently how far some such individuals are actually living outside of the Lord's will.
I have things in my life that I know are not aligned to the Lord's will, and yet I keep them in my life. I am incapable of getting them out of my life, and I'm sure there are other things I don't even recognize that are the same. As a result, I have hardships. Jesus knew I'd have hardships. The good news is that my failure doesn't affect my salvation by faith. The truth is that my failure does affect my worldly life.
Prayer: Lord, I know I cannot be perfect. I cannot expel all badness from my life, take every thought so captive that I never have even a thought outside of yours, and align every single action to exactly what you would have me do. Please forgive my weakness and the actions and thoughts it causes. I do not seek protection, I only seek to know you more. Amen.
