Yes but no need now and some people don't like Christianity.
Unlike the Old Testament or even the New Testament, your belief in God is not something you wear or carry around on your sleeve (shoulders) for everyone to see. ( in this world )
Your belief is in your mind and your heart. Your true enemy is not the people who
do not like Christianity)
The bible states that we fight not against flesh and blood but against principalities and powers of darkness.
Eph_6:12 For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.
Your true enemy is yourself. The lust of your flesh.
1John 2:15
Love not the world, neither the things that are in the world. If any man love the world, the love of the Father is not in him.
1John 2:16 For all that is in the world,
the lust of the flesh, and
the lust of the eyes, and
the pride of life, is not of the Father, but is of the world.
1John 2:17 And the world passeth away, and the lust thereof: but
he that doeth the will of God abideth for ever.
Study these verses and go back and humbly search the scriptures (the bible, in your own language, preferably the king James version, but any version will do for now, if you do not have the king James version)
Jesus's words are of paramount importance as they transcend all time and place. If you do receive the Spirit of God in your life, then the same words you read will overtime take on more and more profound meanings, not because you are a smart student, but only because of your fear of God and He in return will honor you.
