The word estimation is defined as the process of finding an estimate, or approximation, which is a value that is usable for some purpose. Simply put its a judgment or an opinion. Philippians 2:3 says; "Let nothing be done through selfish ambition or conceit, but in lowliness of mind let each esteem others better than himself." As you go through life today, make sure your estimation, judgment and opinion of others, is to esteem them better than yourself.
