In our culture today you won't get much backlash if you talk about God.
Some of you are thinking, "Yeah, right" But stay with me. Our culture has little problem with God, if fact, our culture accepts much talk about God. However, bring Jesus into the conversation and you get a different reaction.
Jesus divides people.
"Do not suppose that I have come to bring peace to the earth. I did not come to bring peace, but a sword. For I have come to turn
'a man against his father,
a daughter against her mother,
a daughter-in-law against her mother-in-law
a man's enemies will be the members of his own household.'" Matthew 10:34-36
This does not mean that Jesus did not come to bring people from every race, tribe and tongue; but it does mean that the person of Jesus will divide people.
The church today must be Christocentric rather than Theocentric (Christ centered rather than God the Father centric). Not because the person of the Son is more important than the other two persons of the Trinity, but because Jesus is what sets Christianity apart from every other religion in the world.
"In the past God spoke to our forefathers through the prophets at many times and in various ways, but in these last days He has spoken to us by His Son, whom He appointed heir of all things, and through whom He made the universe. The Son is the radiance of God's glory and the exact representation of His being, sustaining all things by His powerful word..." Hebrews 1: 1-3a
Jesus is God. He is the EXACT representation of His being. He IS the radiance of God's glory.
When we speak of God many will find common ground, or so they think, because "we all worship the same God." But when we speak of Jesus we say that only a God who is Jesus is God. All other gods are false. This is highly offensive to the world, but absolutely essential to Christianity. So, if someone says they worship the same God as you, ask them if Jesus is God. If they say "No" then you are not worshipping the same God/god; they are worshipping a false god.
The book of Hebrews invites us to make Jesus supreme (because He is). It invites us to hold fast to all that Jesus is. We Christians must take up this call. We must be Christocentric.
Take time to read Hebrews chapter one. And as you speak of your faith speak of Jesus today.
