My chickens won't come out of the henhouse when it's snowing. What holds you back from doing certain things? For me, sometimes I don't want to be uncomfortable, or I'm feeling lazy, or I just don't want to.
Jesus said, "As long as it is day, we must do the works of Him who sent Me. Night is coming, when no one can work. While I am in the world, I am the light of the world" (John 9:4-5).
