Hi Rhino, Thanks for sharing what's going on in your life and being real and honest. I'm not sure I have anything that will help, but my thoughts are that you may not be seeing the greater purpose in your life. It's great that you believe in God. It's also great that you know reaching out to Him in search of a closer relationship with Him is important. I realize that you say, you don't find yourself reaching out... but I am guessing you will eventually. It sounds like you are right on the edge of doing so. When you do, I am guessing you will find it to be profound. When you knock...the door is opened.
We are all part of a grand purpose that God has. Our role is to answer the supreme calling; "Be you perfect, even as I am perfect." We are to seek to move in the direction of perfection. To take the example that Jesus gave for a life of love for His fellow man, and surrender to God's will and of close communion with God and try to follow it. As we learn to understand our fellow man, this understanding (from his point of view) leads to respect, which develops into affection and matures into love. As we seek to do this we are in sync with God's will. Our job is to love God with all our heart, mind and stength and to love our neighbor as ourselves. As we do this, we are then on the pathway to God and we are participating in His great plan for our lives. That plan involves spiritual growth through a long evolutionary process (in this life and beyond), that is filled with joy, satisfaction, adventure (and yes; also challenges, adversity and hardship which fosters growth). If we persevere, one day we will stand in God's presence and experience the unimaginable euphoria of His divine presence. Until that time, we have His spirit which lives within us to guide us. The spirit presence of God within us is an amazing thing which, once we fully digest is truly amazing.
"The goal of eternity is ahead! The adventure of divinity attainment lies before you! The race for perfection is on! whosoever will may enter, and certain victory will crown the efforts of every human being who will run the race of faith and trust, depending every step of the way on the leading of the indwelling Adjuster [God's Spirit] and on the guidance of that good spirit of the Universe Son [The Spirit of Truth], which so freely has been poured out upon all flesh." The Urantia Book.
God has given us all free will which if exercised in the pursue of truth, beauty and goodness, will contribute to the accomplishment of God's plan. Being in partnership with God is not trivial. It is a life of profound purpose. Life isn't about the things of the world. Life is about chosing the things of the spirit... "running the good race".
I recommend you reach out to God in prayer. If you want, let me know and I'll pray with you. Wishing you all the best in finding the meaning that apears to be missing (but is just temporarily out of sight).
