It's pretty simple, but also rather difficult. Spiritual practices/disciplines really are ways we commune with God and make our lives/relationships with Him better or stronger or sweeter. What are those? Things like reading/studying your Bible, praying every day (and all throughout the day...in and under different feelings and circumstances), speaking with God, not just in thanking Him or asking Him for something, but just telling Him how you think and feel...venting with Him, arguing (if necessary) with Him... That's how you grow in a relationship with a person, and God is similar in that regard, intercession for others and things going on in the world, eating with Him, worship is another way, and being in fellowship/mission with other believers. Learn about Him, not just from people, but from God Himself. He'll speak to your, show you, guide you, teach you, help you, and more than I could express. That's all largely up to you, though. You have to choose Him, and make Him your priority.
