One thing have I desired of the Lord that will I seek after; that I may dwell in the house of the Lord all the days of my life, to behold the beauty of the Lord, and to inquire in this temple(Psalm 27:4). David was really a man after GOD's heart, he knew the exact things to say to GOD to make their relationship better again.
David was a man that sought nothing but GOD, just to know Him, to know who "GOD" really was. He was in love with a GOD he couldn't see but trusted His power. David's heart was drawn to GOD. He acknowledged he was nothing and he always went back to GOD for restructuring; that is a man that knows he is limited and needs to make his heart clean to get it right with GOD once more. He knew his life was dependent on GOD.
The one thing anyone can desire is to be close to GOD, knowing and loving this supernatural being. There is nothing that is as sweet as having a beautiful assured relationship with the trinity; with that you know you are assured of eternity with them.
Being close to GOD brings benefit to us(see John 14:23). You can't be close to GOD and be a failure, you can't be close to GOD and not know peace. Many people do not understand that why some things happen to them is as a result of leaving GOD out of their affairs. While Proverbs 3:5-8 tells us to acknowledge GOD in all our ways, GOD expects us to talk to Him, involve Him in all that we do on a daily basis.
GOD wants us to know Him more than we already do.
He wants us to grow past the knowledge we get from sermons preached on Sundays in our local churches. He wants to have a relationship with you, GOD is not about your attendance in church, He is about your love for Him. Your love for Him automatically drives you to His presence. It makes you do things for Him, not for your pastor, no for anybody.
Do you know you can be regular in church and not be regular to GOD? The book of Revelations 2:19-20 tells us that GOD knows about our service and everything we do in the church, but nevertheless there are few things that oppose that.
I wouldn't desire anything more than knowing GOD. You will find yourself in some situations and you know you are helpless all that you need to do is run back to GOD, who knows how to calm the body, soul and spirit.
Although I see it as taking GOD as the last option. I don't want to see GOD that way. I want Him to be the first and first(funny!). GOD should be at the centre of your heart all day, everyday. He shouldn't be replaced by anything or any activity.
In the end, getting close to GOD benefits us than anyone else. Jesus waits and hopes that you take His hand and walk the walk with Him.
Jesus loves you.
