Conforming? Salt & Light?

I seem to be so full of words tonight, but I will try to articulate what I feel God is sharing with me.
Romans 12:2 says And do not be conformed to this world but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God.

The life lesson, as stated in my Life Principles Bible says God does not want us to try hard to sin less, but to depend upon His Spirit to be transformed into people who love to please God through willing obedience. That transformation begins with the mind.

Then it says in Matthew 5:13 that You are the salt of the earth; but it the salt loses its flavor, how shall it be seasoned? It is then good for nothing but to be thrown out and trampled underfoot by men.

And again the life lesson states that Jesus wants us to take seriously our role as "salt," a preservative. Our behavior is to be distinctly different from those who do not know God, and it must not reflect the same kinds of sin that corrupt a godless culture.

Now, not to harp on the words that were spoken to me concerning my children, but as a dear friend pointed out to me, my children are considered dumb/stupid, simply because they don't know the ways of the world. Now I will be the first to admit that their math level is not where public school children are, but I don't see any of my children cringing when it comes time to pull out the math books either. They may not be perfect spellers, but I don't see them hesitating to use a dictionary to learn to spell a word.

I have given my children the opportunity to learn ANYTHING, when I equipped them to read and have a love for learning. There is NOTHING in this world they cannot learn, all it takes is picking up a book and reading & studying on whatever it is that piques their interest.
What brings me the most joy is when I say go get your Bibles and they are running and smiling as they go to get them.

I don't mince words here, If my children NEVER learn the things of this world and all that the world says is important and necessary for life, but they have a relationship with Christ and walk with Him moment by moment and day by day, I have fulfilled my purpose in their lives.
