The life with Christ has nothing to do with being in a "church" atmosphere for all eternity. God’s salvation involves far more. He is planning to make his children productive, creative, useful, and supremely happy, within an environment of spiritual perfection, health, peace, and love.


A member of a Christian Church should support all social initiatives having a purpose to maintain and strengthen well-being and progress of the whole community and its members.


Loss, fear, grief or guilt may be weighing someone down. Never give up. Keep up with the search of truth in yourself and you will be awarded with the sense of happiness and joy you are looking for.
