God tells us in His Word through Isaiah that the earth is round. In the days of Columbus the people were convinced the earth was flat. They only focused on what they could see with their eyes and did not believe what God said about the earth in the scriptures.
Isaiah 40:22
It is He who sits above the circle of the earth, And its inhabitants are like grasshoppers, Who stretches out the heavens like a curtain, And spreads them out like a tent to dwell in.
What falsehood in your life today are you believing that is not true? Read the Word! Everything you will ever need to know is in the Word of God.
Just because you are convinced something is true does not make it true…..
