What differences will being a Christian make in this life? Am not so sure off the question but i will give a general idea of to people a christian and a none christian sometimes they might look alike or having same life in you face but the is a big difference to their life and action now we don't talk about church goes but real christian
In the beginning of all things God created everything and he sate down and looked at the earth he released it was lonely something was missing and he said lets create a man in our on image then Adam was created " God never appeared in flesh but he is a spirit being" what dose this means to me and you simple we are of the spirit but not flesh.
The difference of being a christian in this life is where by you get more understanding of real who you are. This activate your spirit being because by know who you are you will be able to empower you real being over your flesh as it says "dust to dust, Spirit to Spirit"
God himself sent a massage saying fear not the one who destroys or kills the flesh than he who destroys or kill the spirit when you die in this world you have only separated from the flesh now to go to your original home
In some scriptures God said for these things you call them temple they are not my temple you build them for your own interest not mine i have my own temple that i have built with my own hands God was in that massage referring to the body.
A well equipped Christian know how to behave in an situation because he is not lead by emotions or feelings but by the spirit of God that lives in him his heart is filled with joy love peace self control and humbleness which leads to righteousness
And the word Christian means Christ like
Be blessed
