In order to achieve spiritual victory, you must practice self-denial in all areas of life. This is an active way to die to self. But always be careful to deny yourself for the Lord, in order to better follow Him. You may start with giving up Cokes and putting the money in a special missions offering. You may want to give up a football game for a time of special Bible study or prayer. This is also where fasting comes in as a spiritual exercise. Fasting is going without food for a period of time.
For the Christian, it is going without food in order to better concentrate on the Word and prayer. There are sound scientific and medical principles behind fasting, but if your purpose is not to glorify the Lord, it does not count as a genuine spiritual exercise.
How about giving up that new dress or even your car so that you could give a special offering to the Lord? You will not begin to experience the richest spiritual blessings of the Lord until you begin to sacrificially follow Him. This takes real discipline… but the rewards are well worth the effort.
Actively work to develop good character qualities. Make a list of the qualities you find in God’s Word: honesty, uprightness, humility, wisdom, gentleness with people, etc. Proverbs provides an excellent source for character qualities. Start with the one that you feel you lack the most. Begin to pray that God would develop this quality in your life. Memorize scriptures that refer to it. Look for opportunities to express that quality in your life. God will provide those opportunities. Do it every day. Keep track of your progress.
When that quality has been developed, go on to another quality. This is such a valuable discipline. And it is so much more than self-improvement. God is actually doing the improving within you as you learn His Word and live it in your life. Be especially alert to pride creeping in as you see yourself developing. Remember, it is God’s work and He must receive all praise. You are merely letting Him be Himself in your life.
Spiritual victory is not the impossible dream of the Christian. Neither is it an easily attained goal. It is waiting for anyone who loves God enough to take Him at His Word and obey that Word with all of his heart, soul, and strength.
