I am subscribed to Joel Osteen's daily devotion by email, and today he said something that was worded so well for the point I am always trying to drive home. "The key is to keep moving forward in your spiritual journey one step at a time. Keep your eyes forward and don’t get stuck in the past." I love this because there is no mention of quitting and starting over. He says to not look back.
When you become a christian, you never go back and get stuck in the past. You may hit some bumps in the road, take some wrong turns, get way off track and need help finding your way back, but you never get stuck in your past. You always try to be better. Try to do better. And although, at times, you may get stuck in one place in your walk for a time, you regroup, pull it together, learn from your mistakes, and keep moving forward.
Your health and fitness journey resembles this so much. It's a day to day thing. You take it one day at a time. "The key is to keep moving forward"!! Don't take your eyes off of what's ahead of you. Don't look back, unless its to see how far you've come. Don't let doubts and fears keep you down. If you have a speed bump, deal with whatever it is and continue on when you're able. Just never get stuck in the past. You don't belong there.
Pray about your journey. God gives us strength in everything we need it for. And He wants you to take care of yourself. He will provide you with what you need to keep going.
