For a Christian, the presence of God ought to be everything. Go through scriptures. Everything God does is tied to where His presence is. Including His provision. Including His promises. His covenants.
When we enter into covenant with God, for anything, it is always dependent upon His Presence. You do what you’re supposed to, and seek His presence at all times, and everything else falls into place. I’m not saying that it’ll be easy. There will still be tough times. But you seek His presence, and even in the valleys, He’ll never fail. You’ll look back, and not understand what happened or how, but you’ll know God provided in that time.
So how do we seek His presence? Well, I’m glad you asked. It’s simple, but not easy. Pray, praise, worship. Search out the scriptures on each of these, and find out how God desires these to be done. Each one. Do it that way. You’ll find His presence falls when you do what He says.
