This little fella looks happy! Remember happiness? Its being young and waking up on a warm spring day in the month of May... feeling great!!! Perhaps its the day you bought your first car or house or maybe the day you became a parent? Those things come and go, but this little passage from the New Testament says it all for me...
WEB: Philippians Chapter 4
 Rejoice in the Lord always! Again I will say, “Rejoice!”  Let your gentleness be known to all men. The Lord is at hand.  In nothing be anxious, but in everything, by prayer and petition with thanksgiving, let your requests be made known to God.  And the peace of God, which surpasses all understanding, will guard your hearts and your thoughts in Christ Jesus.
Many things have changed in my life, but God has not changed. He is right where he has always been and the knowledge of that makes even the worst day something to remember. If you can't say that right now, then perhaps its time to do something about the situation. Take some time, reflect on where you are in relation to God. Open the book, ask someone who says they are a Christian; do something about it. You will be glad you did; maybe even as glad as the little guy in this picture!!!
