Nothing is for certain. We can have our life planned down to the very minute and in a second it can all change. A loved one tragically dies, we lose our job, home, a good investment turns bad, a friend betrays us, we make a fateful decision, the list goes on.
If you have faith, as small as a mustard seed, you will come out on the other side. But the most solid foundation of faith can and is tested from time to time, no one is immune.
Hebrews 11:1 What is faith? It is the confident assurance that something we want is going to happen. It is the certainty that what we hope for is waiting for us, even though we cannot see it up ahead.
