Why I am thankful for gravity (or, the necessity of absolutes)

Can you imagine a world with no absolutes?  A world in which gravity was only a suggestion and at random intervals throughout any given day you could being to float aimlessly in space does not sound like a glorious place to be.  Or have you considered living in a world in which every action did not have an equal and opposite reaction?  Imagine going to a door and pushing to no avail.  Then you read the sign that says "pull" and laugh at yourself and pull the door only to have it remain shut.  The door is not locked, but no matter how much force you exert, there is no requirement that the door open.  A world without absolutes becomes chaotic and scary!  I am glad that I do not have to worry about floating off into space - gravity will always keep me planted on terra firma. 
It is interesting to me that humanity generally accepts these absolutes and is even grateful for them, but when it comes to morality humanity scoffs at the idea that a moral code could be absolute.  We know that gravity and thermodynamics provide an orderly world in which random forces do not upend us.  They protect us.  But moral absolutes are seen as being of a different nature altogether.  This is not surprising when you read and understand Romans 1.  But what is surprising is how often Christians deny the authority and presence of absolute truth in the way that they wander and may believe whatever wind of doctrine happens to be floating by.  Instead of grounding ourselves with the truth of the Word of God we find ourselves floating in the nebulous caverns of the spaciousness of false teaching. 
We become tentative and scared to say something that might offend instead of speaking the truth in love.  We become fearful of what someone might say or think.  Or we just assume we do not know enough to speak truth.  May I propose an alternative?  1 John 4:4 tells us "You are from God, little children and have overcome them; because greater is He who is in you than he who is in the world." (NASB)  If what we are proclaiming is an absolute it is because it has its source in God and God's Word.  And if it is absolute, than we should be willing to proclaim it boldly recognizing that God is greater than whatever the world may throw at us.  This is why it is so critical as Christians to speak as authoritative only what the Word of God says.  But we must speak it. And in order to speak it we must know it.  And in order to know it we must study what God's Word says.  And when we see the truth that is revealed, we must be willing to proclaim it boldly - because a world without absolutes (even moral ones) is an incredibly scary place.
