I think sometimes we have to just keep our goal ever before us. Don't spend as much time looking back at where we where, but look at the progress we are making towards where we want to be. For me, it is like those last few miles of a road trip. The promise of MY shower and MY bed keeps me going, I keep focused on the tangible reward at the end of the journey. It is amazing what we human being can do if we focus on the task ahead of us.
As an artist and a minister it is always a challenge for me to balance my need for solitude and study with my call to be of service in a hurting world. I haven't been doing well lately at all! And I believe it is beginning to show in my work. The less time I spend feeding my spirit the less effective I become at feeding others and the effect is like my son's checking account, my body writes checks that my spritual reserves just can't cash!
Sometimes the checks are to big to correct easily. In those cases, time apart may give you a place to plan how to get back on track, not give you time to forget the problem, but to pray for recommitment to the goal and refocusing on God's will for your life. Just always remember that God can use you in any circumstances you find yourself, even when it is the mud and mire on the side of the path you never meant to travel.
