prayer and worship always strengthens my relationship with God. i feel closest to him during those times and i carry him with me after wards. if you take time out to just worship and pray with him you'll feel stronger.
but you have to make sure you're doing to consistently. not just like twice a week. every day (which is hard at first but you'll get used to it) your relationship will grow. but make sure you're reading your bible too and learning more about him. ^_^
Spirituality although in Sync with the Fleshly World in some Forms, is a World of its Own...becoming more Spiritual the more Different Doors will open.
You want to become more Spiritual but dont know what awaits you wenn you reach a new lvl of Spirituality?....Jesus Christ does as he pleases, while taking in consideration that he will only allow things in our life that we can handle.
You are Spiritual Weak?, then if you want to become a more Spiritual Person you must know what awaits you in that Realm. Light.....Darkness.......Angles.....Demons........being Awake while you notice most Christians are Asleep "Spiritualy".....Voice of Jesus Christ.........Voice of Demons.....Revelations about Man....Works....and more.
Read the Bible Pray to learn what awaits you in this Spiritual Realm, Jesus Christ can see what Man were Thinking, and what was in there Hearts....what if you suddenly see that also?...i tell you the Hearts and Thoughts of Man are not all Butterflies and Flowers.
I hope you get what you Desire, but you must Learn more about what awaits you and believe it.
