Humanism is an outlook or system of thought attaching prime importance to human rather than divine or supernatural matters. Humanist beliefs stress the potential value and goodness of human beings, emphasize common human needs and seek solely rational ways of solving human problems.
Christianity, on the other hand, attaches prime importance to God and God's word, the inspired teachings of God (Bible), to be the foundation of everything we think, say and do.
For a soul to gain salvation, adoption of the humanism philosophy is not for you.
