Happy is he that hath the God of Jacob for his help, whose hope is in the LORD his God: ( Psalms 146:5 KJV)
Happiness is my choice. It's your choice too!
As individuals, we can choose whether we want to constantly live an unhappy life or we want to live happy and benefit from all the inheritance of blessings that God has in store for us. When persons trust in man, they end up in some very miserable and trying situations, while those who HOPE and TRUST in God remain HAPPY inspite of and despite of.
While we were born into a Dark sinful world from the moment Adam sinned, Jesus offers us a FRESH LIFE and LIGHT which brings happiness. I like how Adam Clarke put it in his commentary on that particular verse. "But he that has the God for his help who helped Jacob in his distress, and was with him, and sustained him in and through all adversities, can never be destitute; for this God changes not; he lives for ever, and his projects cannot perish.)
Note: God never changes, so don't get down and walk around with a sad face. Just wait on him and enjoy your happiness moving forward.
