The first warning sign of loss of spiritual desire is the “have to” mentality. You look at things as an obligation and not as a gift to be able to accomplish for the Lord (“want to” mentality).
Loss of Spiritual desire is an indication of an attack from the enemy. It is his desire to pull you away from reading your bible, praying, going to church, fellowshipping. Satan is patient, he will slowly draw you away.
You need to be intentional every day, “Now set your heart and your soul to seek the Lord your God….” 1 Chronicles 22:19
