Hebrews 3:13 says But exhort one another every day, as long as it is called “today,” that none of you may be hardened by the deceitfulness of sin.
Understand that this world doesn't want you to get any joy out of your day or any day for that matter. This world, which is full of sin and disobedience against God, is determined to destroy you and everything around you. That includes your hope for this day.
The writer of Hebrews tells us how to counter this nonsense. Exhort or encourage each other. If you want encouragement, help someone. Smile at everyone. Greet people with a cheerful hello. Ask if you can help someone today. Just give what you want, and God will return everything to you with more to spare.
PRAY: Dear Jesus, help me to help others day. AMEN
