Psalm 16:8 says,
“I have set the Lord continually before me; because He is at my right hand, I will not be shaken.”
The Psalmist is explaining because he places God first in his life he knows God is present. To be at his right hand means God is ready to help him if needed, therefore he will not be shaken by the troubles around him. When we place Jesus first in our lives we can rest knowing He is present to help in times of trouble.
