Yes, I do have advice!
What really helped me when I realized the ‘Jesus deficiency’ in my life is that I began to study Jesus. The beginning to any relationship is getting to know the other person – what do they like, dislike, what are their views, where do they come from, how do they think. Basically we courted haha. And the more I got to know him, the closer I felt to him. The deeper i fell in love with him and fully came to grasp who he is and what it is he did for me. And knowing him intimately is what makes the difference between simply practicing a religion and really living life the way God intended us to.
