Spiritual Growth Does not Come Naturally
The mind of sinful man is death, but the mind controlled by the Spirit is life and peace: Romans 8:6
Physical growth is nature’s way of allowing your body to develop. Your spiritual nature needs to grow too. Many people ignore this important aspect of their lives because it cannot be observed or measured like your body can. Yet, that does not make it any less important.
The greatest Guide and Adviser that you could ever find is Jesus Christ. He is the revelation of the living God and therefore has a perfect understanding of the problems that you wrestle with. Having a desire for oneness with Christ and yearning for a deeper relationship with Him will result in spiritual growth if you surrender to God completely.
