May the God of hope fill you with all joy and peace in believing, that you may abound in hope by the power of the Holy Spirit. - Romans 15:13, NKJV
Joy is supremely different than happiness. Happiness, which is an American’s inalienable right to pursue, seems to depend more on circumstances or things or people or feelings. Joy is independent of everything except our relationship with God. Someone has defined joy as peace dancing! And Jesus, with eyes that must have sparkled in anticipation of the blessing that His beloved friends were going to receive, explained, “I have told you this so that my joy may be in you and that your joy may be complete” (John 15:11, NIV).
One of the hallmarks of those who are immersed in a love relationship with Jesus and His Father, which they express through abiding obedience, is joy! Joy in Jesus! Joy in living our lives for Him! Joy in abiding . . . and obeying! Joy that is complete, with nothing that needs to be added to make it more so.
