We need to continually surge forward spiritually, to prevent sliding backward. I discovered recently that the Australian coat of arms has a picture of an emu and a kangaroo. They chose those particular animals because they both share a common trait that appealed to the Australian forefathers. Emus and kangaroos can only move forward. They cannot move backward. The three-toed foot of the emu makes it fall if the emu steps back, and the kangaroo’s large tail prevents it from moving backward. People who choose to really follow Jesus and be his disciple become like the emu and the kangaroo, moving forward only, and never backward.
By accepting Jesus and moving forward with him through the action of the Holy Spirit within us, we are brought into his kingdom. We can’t get there on our own.
