"Do not let them depart from your sight, Keep them in the midst of your heart."
At the beginning of Chapter 4 see wee that this instructions from a father. We should remember what our parents say to us but this goes much deeper,this is from our heavenly father. In verse 20 it says "Give attention to my words", there is no doubt that we are to keep God's Word close to us. How else are we going to get to hear what He has to say to us? We should have a Bible at close range always. When you are happy, pick it up. When you are sad, pick it up. God always had something for us. This is where we can find peace, joy and love. And if you don't have one near you then sing praise songs, most of what we hear are God's words put to song. For us to grow as Christians we have to be nurtured, feed daily on the word of God, listen to His music, this is the best way for you to keep a good attitude, a good spirit, and for you to just enjoy your day. Always remember that your attitude is actually a choice, you can choose to be in a bad mood or you can choose to be happy. I don't think that you can stay in a bad mood when you are taking in God's word. What do you choose today?
