Your past can be a hinderance to the glorious future that God has planned for you, if you allow it. You cannot afford to wallow in past defeats and allow those defeats to stop you from making progress. Remember that you an overcomer - 1 John 5:4; you are destined to win. Defeats don't define you. Rather turn them around into learning opportunities.
Likewise you cannot afford to let the celebration of past victories to cause stagnation in your life. Thank God for the successes that you have had in the past. However there is much more that God has in store for you. If you refuse to move past your past successes then your ability to win more battles in the future is compromised.
Apostle Paul set the example. He chose to keep forging ahead rather stay in the past - Php 3:13. He knew that greater things lay ahead that what he had already experienced. Likewise you must not stop pressing in and pressing on so that you can lay hold of that glorious future that God has planned for you. Forget those things that have happened in your past so that you can claim new victories.
Have an exceptional day!
