Sacrifice. Jesus was and is the ultimate sacrifice. He gave up His whole life for us and would do it again. In my work, I made a desert background to represent that even when we feel alone (ie in the middle of the desert, and lost) He will be there. No matter how we feel. In the depths of feeling like we should give up and we have no way forward, we do. We always do. Through and with Jesus. Because of His sacrifice. (This is my personal beliefs. No harm if you don’t believe or feel the same.)
