How many times have you compartmentalized faith as a part of your life? It can be so easy to have that 5, 10, or 15 minute quiet time in the morning or at night (check it off the list), go to church for a couple hours on the weekend, and then more or less not include God in the rest of your day/week.
Proverbs 3:5-6 says, "Trust in the Lord with all your heart, and do not lean on your own understanding; in all your ways acknowledge Him and He will make your paths straight." "All your ways" means all, Not just some but all. On a practical level, that means staying in a constant mindset of conversation with God. As you're driving to work, before that conference call, when you're making a difficult decision, while you're standing in line at the grocery store, as you're talking with people. At all times.
When we get in this habit of praying continually -I Thessalonians 5:17, we can really involve God in all aspects of our life and not act as if he's just a minor player in it. He becomes intricately woven throughout our lives and we more clearly hear from Him as He guides our steps.
A really short but good book on this topic is The Practice of the Presence of God by Brother Lawrence.
