Happiness is a temporary emotion founded upon circumstances. Joy is a lasting emotion founded upon the Word of God.
Regardless of our circumstances we can KNOW that according to Romans 8:28 "And we know that God causes everything to work together for the good of those who love God and are called according to his purpose for them." No matter what you situation is today,
God loves you and He does want to come and work within your circumstances. But you must invite Him to come in and work on your behalf. First, acknownledge Jesus Christ as the son of God and ask Him to forgive you. Second, ask God to take complete control of your life. Thirdly, begin to thank God that He will lead and guide you through your circumstances.
Joy Will Come! It is on the way even now!!
