Perhaps this is the reason why we can become so stressed out during the week. We only give thanks to God on Fridays.
Look, however, at what the Bible says: This is the day the LORD has made; we will rejoice and be glad in it -Psalm 118:24.
Look at another verse: Therefore by Him let us continually offer the sacrifice of praise to God, that is, the fruit of our lips, giving thanks to His name -Hebrews 13:15.
It's all about cultivating an attitude of gratitude. When we are always thankful to God, no matter what day it is, we enjoy the day more. When we enjoy the day, less stress comes into our lives. When we are less stressed, we are able to forget about our needs and wants and be of service to others. This is the best way to evangelize.
It's also the best way to live abundantly.
