Our faith is put to test the most when tribulations come our way. If rainy days do not come an umbrella would be of no use. In other words it is at times like this that we are differentiated from unbelievers depending on our reactions at the arrival of these times. Tribulations are something that was bound to occur in this earth.
The enemy, the devil, never wants anything good for the people of God. Some people see tribulations to be the end of the world. But it is both really so because the word of God tells us otherwise.
Romans 5:3 - And not only so, but we glory in tribulations also: knowing that tribulation worketh patience;
4 - And patience, experience; and experience, hope
Tough times create room for these virtues to come into manifestation. It is at these times that we build up strength, stamina and capacity as christians. What this is trying to tell us in essence is that in everything we should thank God and give Him glory.
