Psalm 59:17
Unto thee, O my strength, will I sing: for God is my defence, and the god of my mercy.

Christians need not live in fear. The most powerful force we could imagine is but a bug against the cyclone of our eternal God. We can sing, we can rejoice, even in the darkest hour and in the most troublesome times. By no means will we always be happy, and our hearts will often be broken. But our inner strength comes from God. We are surrounded by the power of almighty God – He who never fails. Trust Him.
