What man is he that feareth the LORD? Psalms 25:12a
Are you obsessed by something? You will probably say, “No, by nothing,” but all of us are obsessed by something— usually by ourselves, or, if we are Christians, by our own experience of the Christian life. But the psalmist says that we are to be obsessed by God. The abiding awareness of the Christian life is to be God Himself, not just thoughts about Him. The total being of our life inside and out is to be absolutely obsessed by the presence of God. A child’s awareness is so absorbed in his mother that although he is not consciously thinking of her, when a problem arises, the abiding relationship is that with the mother. In that same way, we are to “live and move and have our being” in God (Acts 17:28), looking at everything in relation to Him, because our abiding awareness of Him continually pushes itself to the forefront of our lives.
If we are obsessed by God, nothing else can get into our lives— not concerns, nor tribulation, nor worries. And now we understand why our Lord so emphasized the sin of worrying. How can we dare to be so absolutely unbelieving when God totally surrounds us? To be obsessed by God is to have an effective barricade against all the assaults of the enemy.
