One vital means of growing closer to someone is spending time with them– having meaningful conversations, and in some cases, sharing experiences. The same is true of our relationship with Abba Father. He speaks to us through His Word; we communicate to Him through prayer, praise, and worship.
Basically, the devotional life is a perpetual habit of setting aside time to sit at the feet of our risen Lord and Savior, Jesus Christ. This deliberate and consistent practice requires persistency and commitment but doesn’t have a designated process or duration; it’s borne out of a relationship.
