Two of Australia's indigenous creatures, kangaroos and emus, have something in common - they seldom move backward. Kangaroos, because of the shape of their body and the length of their strong tail, can bounce along with forward movement, but they cannot shift easily into reverse. Emus can run fast on their strong legs, but the joints in their knees seem to make backward movement difficult. Both animals appear on Australia's coat of arms as a symbol that the nation is to be ever moving forward and making progress.
The apostle Paul called for a similar approach to the life of faith in his letter to the Philippians: "Brethren, I do not count myself to have apprehended; but one thing I do, forgetting those things which are behind and reaching forward to those things which are ahead, I press toward the goal for the prize of the upward call of God in Christ Jesus" (3:13-14). While it is wise to learn from the past, we shouldn't live in the past. We cannot redo or undo the past, but by God's grace we can press forward and serve God faithfully today and in the future. The life of faith is a journey forward as we become like Christ.
