We often misunderstand 'Joy' as being 'happy'. However it runs a lot deeper than simply being happy. Being happy is an emotional state of being, but Joy is a fruit of God's Spirit living within us. So, in a simplistic way - we can be filled with Joy, but not feel happy. It does seem strange, but I wonder how you feel about that?
Here are a few other thoughts on Joy:
"But the Holy Spirit produces this kind of fruit in our lives: love, joy, peace, patience, kindness, goodness, faithfulness,gentleness, and self-control." - Galatians 5:22-23
“Joy is the by-product of obedience.” - Traditional.
"Joy is prayer; joy is strength: joy is love; joy is a
net of love by which you can catch souls." - Mother Teresa
May you experience God's JOY in your heart today D3LM3
