spir•i•tu•al (spĭr’ĭ-chōō-əl) adj. — Of, relating to, consisting of, or having the nature of spirit; not tangible or material.
We are all spiritual beings. We have physical bodies, but our lives are largely driven by an unseen part of us. There is an immaterial center in us that shapes the way we see the world and ourselves, directs the choices we make, and guides our actions. Our spirit is the most important part of who we are. And yet we rarely spend time developing our inner life. That’s what spiritual formation is all about.
Spiritual Formation is a process, but it is also a journey through which we open our hearts to a deeper connection with God. We are not bystanders in our spiritual lives, we are active participants with God, who is ever inviting us into relationship with him.
Jesus said, “I came that they may have life and have it abundantly” (Jn. 10:10). We at Renovaré believe that such abundant life is possible here and now, because Jesus showed us the way to it. As we take on the life of Jesus – become like him – we experience a richness in life and faith that is truly renewed day by day (Col. 3:10).
