Happiness comes from spiritual wealth, not material wealth… Happiness comes from giving, not getting. If we try hard to bring happiness to others, we cannot stop it from coming to us also. To get joy, we must give it, and to keep joy, we must scatter it.
Let us therefore come boldly to the throne of grace, that we may obtain mercy and find grace to help in time of need.Hebrews 4:16
If you are thankful, you will not only experience more happiness, but you will experience more blessings to be thankful for.
Refuse to be fearful about what will happen to you. God is faithful and He will take care of you if you trust Him.
