Faith in God is shaken when we blame Him for the free will choices of human beings — or judge Him for the divisive dogmas of man-made religions. But hang onto your faith, and God will repay you by showing you the silver lining He puts inside every tribulation you or the world around you may contrive.
Joyful human fellowship is the will of God, and the desire of every spiritual seeker. However, not every group is right for every person, and what fit well in the past may be outgrown today. Be assured, there is a place for all seekers after truth who crave resonance and support for their Godly aspirations. Those who preserve their faith will find the fellowship they seek.
