Our place of shelter from things that are too difficult for us. Psalm 61:1-4 (Amplified)
Hear my cry, O God; listen to my prayer. From the end of the earth will I cry to You, when my heart is overwhelmed and fainting; lead me to the rock that is higher than I [yes, a rock that is too high for me]. For you have been a shelter and a refuge for me, a strong tower against the adversary. I will dwell in your tabernacle forever; let me find refuge and trust in the shelter of your wings. Selah [pause, and calmly think of that].
