O praise the LORD, All ye nations: Praise him, all ye people. For his merciful kindness is great toward us: And the truth of the LORD endureth for ever. Praise ye the LORD. Psalm 117:1-2 KJV https://bible.com/bible/1/psa.117.1-2.KJV
The entire world knows about God, whether they choose to believe in Him as their Redeemer and their Savior is an entirely different matter. According to the Bible or the Torah, God created the universe in six days and rested on the seventh. Although many people deny the truth found in the Bible, one day they will be shown the error of their thinking. The reason that I find it strange that people choose not to believe in God is that they call on Him when there is a dire need in their life. Sudden death or illness in their family will cause even the most devout atheist to seek help from a Higher Power.
Why should we praise Him every day? Because He placed each of us here for a reason and it is our job to seek Him for that reason and become the person to fulfill it. God gives each of us a certain number of days and years to live and only He knows how many we have. If you woke up this morning and you are reading this then you have today to praise Him and be useful to Him for today. You don’t know if you will have tomorrow but He has given you today, so do your best to be useful to Him today!
