If you seem to have so much fighting to do, it may be because you did not have one sharp, decisive battle to begin with. It is far easier to have one great battle than to keep on skirmishing all your life. There have been some of us who spend decades fighting what may be called the besetting sin, and on that one sin has been wasted enough strength to evangelize the world.
Does it pay to throw away your lives? Why not have one battle, one victory and then praise God. There is labor to enter in. The height is steep; the way of the cross is not an easy way. It is hard to enter in, but having entered in, there is perfect rest. "and when He giveth you rest from all your enemies round about" (Deuteronomy 12:10). May God help us and give us His perfect rest.
However, after saying that, we must realize that the Christian life is not a one-time decision, it is a long-term relationship. Yes, there are crisis points - such as being born again and being cleansed by the fullness of the Holy Spirit. But God does not save us so we can sit. There are journeys to take, relationships to develop, and a soul to grow. This journey is about making progress! What a great adventure this is. but it does start with a decisive battle.
Be blessed today, and do not forget that you are loved!!!
