My guinea pigs know where their help comes from. When I go near their cage, open the refrigerator, crinkle a plastic bag, or do pretty much do anything within their hearing range, they squeal because they think I'm going to feed them. Guinea pigs do not easily trust people but once guinea pigs learn who brings them food, they learn to trust that person. Because I feed my guinea pigs every day at the same times, they have learned they can absolutely trust me to help them when they feel hungry.
I should know where my help comes from. I should already have learned from all the times God has helped me before and know that right now He is still going to help me because I'm still trying to stay under His care. I should know (because I'm more advanced than a guinea pig) but I still struggle with remembering where my help comes from whenever I feel scared. Instead of just lifting up my head and squealing to God (like my guinea pigs do to me), I worry and wonder what will happen or what I should do. I should know that (like my guinea pigs) I can't take care of myself and God is always nearby to hear my call and come help me.
"I lift my eyes toward the mountains. Where does my help come from? My help comes from the Lord, the Maker of heaven and earth." Psalm 121:1-2 HCSB
