The LORD has chosen Zion, He has desired it for His dwelling. Psalm 132:13

God is my refuge

…my refuge is in God.  Psa. 62:7
 
When we are hidden in His shadow or under His wings, we are protected like a bird from the elements and from the enemy who hunts us down. It's a condition of being safe or sheltered from pursuit, danger or trouble. Refuge is something providing shelter. 

Psalms 46:1 says God is our refuge and strength, an ever present help in trouble.

The Bible does not promise us care-free life or trouble less life. But it ensures a hope amidst the troubles. We have a God to whom we can run and hide under His wings. His Name the powerful name of Jesus is a refuge where no enemy can strike us or attack us. He is our trustworthy God. 
He alone is our refuge.
