I've alwasy heard that kids are sponges, just soaking up all the information that they can. What a true statement!
The question is, are we sponges for God? We are His children and in that place we should be soaking up all of the information that we can about Him and what He wants us to do in our lives.
I believe that we don't really outgrow being sponges. I see us as always soaking up something, be it good or bad.
The concern is, if you've been soaking up the bad stuff of the world. How do you replace it with the good things that come from God?
Think about a dirty sponge, you turn on the clean water and place the sponge under the flow. Does is automatically become clean? NO! You have to squeeze the sponge in order to eliminate the dirty stuff before it can become saturated with the clean water.
That is exactly what God has to do with us. If we have had too much of the world in our lives, He is going to have to squeeze us in order to get rid of the negative and fill us up with His word.
Luke 9:23 And He said to all, If anyone desires to come after Me, let him deny himself and take up his cross daily and follow Me.
Romans 12:2 And do not be conformed to this world, but be transformed by the renewing of your mind, in order to prove by you what is that good and pleasing and perfect will of God.
