Every person on earth needs, every single day, to increase his faith in God. God alone. And every person on earth, likewise, has some crutch they rely on, in which they need to decrease their faith.
It can be anything -- casual reading, natchos, swimming, something far worse such as porn. Nobody can ever have enough faith in God, and all people will, to some degree, have faith in some earthly thing.
Obviously there is nothing wrong with enjoying and making use of wholesome tools provided by God. Again, God commands us to be armed, and there is nothing wrong enjoying a wholesome pursuit like hunting and shooting, and appreciating the capacity for protection, defense, and freedom God provides for us via the keeping of arms.
But God is the end all and be all, a fact that nobody can ever fully embrace with their entire heart soul and being, although we must forever strive to.
"Let he who is without sin cast the first stone."
“all people will, to some degree, have faith in some earthly thing” Earthly “things” are not alive. I have one God and that is God the Father, God the Son, God the Holy Spirit. To say I would put that kind of faith in some “earthly thing”, is ridiculous. I use “earthing things” to help me, not to worship. Guns fall in that “earthy thing” category as well as every thing on earth.
