A feather

Psalm 91:4 "He will cover you with his feathers and under His wings you will find refuge ...". Not only is that a picture of refuge, God is also taking the penalty of all our sins. There is not one human who can say they are completely sinless. Whatever the degree of sin all of us can be covered by God's protection over our lives. He did this by sending His Son, Jesus, to die for us as a sinless man. Remember, John 3:16 "For God so loved the world that He gave His only Son, that whoever believes in Him will not perish but have eternal life".
