Blessed are they which do hunger and thirst after righteousness: for they shall be filled. Matthew 5:6
Unsanctified desire will stop the growth of any Christian life and conversely, purified desires will tend towards righteousness by a kind of gentle moral gravitation.
In the moral world, right desires tend toward life and evil ones toward death— that in essence is the scriptural teaching on this subject!
Whatever a man wants badly enough and persistently enough will determine the man’s character.
Wrong desire perverts the moral judgment so that we are unable to appraise the desired object at its real value. However we try, still a thing looks morally better because we want it. For that reason, our heart is often our worst counselor, for if it is filled with desire it may give us bad advice, pleading the purity of something that is in itself anything but pure!
When our dominant desires are bad the whole life is bad as a consequence.
When the desires are good the life comes up to the level of our desires, provided that we have within us the enabling Spirit.
At the root of all true spiritual growth is a set of right and sanctified desires. The whole Bible teaches that we can have whatever we want badly enough if, it hardly need be said, our desire is according to the will of God!
The desire after God and holiness is back of all real spirituality, and when that desire becomes dominant in the life nothing can prevent us from having what we want. The longing cry of the God-hungry soul can only be, “Oh, to be like Thee!”
