Read Psalms 19:7  There are several big words in this verse, but there are some good things to learn from them.  This verse says that God's Law is perfect.  The Bible is called the Law in the Old Testament part.  The Old Testament part of the Bible is the part that tells about the nation of Israel before Jesus was born.  Some things in our world are pretty good and other things are really good.  But this verse says that the Law of the Lord is perfect.  Perfect means absolutely nothing wrong with it.  None of us are perfect, we usually do a few things wrong.  Nothing in our world is perfect; nothing lasts forever.  But God's Word is perfect.  We can always trust what the Bible says - it is perfect.  Convert means to change for the better.  If we read the Bible and obey what God says for us to do, God will change our hearts.  He will convert us.  When we are saved, we are converted.  We are changed.  We used to like to do bad things, but God converts us and so now we want to do the right things.  We are not perfect like God's Word, but we will be perfect some day when we get to heaven and are with God.  He is changing is every day to be more and more like Him.  The last part of this verse says that God's Law will make wise the simple.  If we don't know exactly what to do or which way to go, God will help us to make the right decision.  He will give us the right way to go.  God will make us wise.  Isn't it good to know that if we listen to God, He will make us to go in the right way!
