You should know better than to say, “Today or tomorrow we will go to the city. We will do business there for a year and make a lot of money!” What do you know about tomorrow?
The original sin was birthed from a desire to be self-sovereign. This is the primary thing that plagues mankind today, the thought that we can determine our own path and be rulers over our own lives. Satan was booted out of heaven for this offense. A fully submitted life is the only life God will accept. Always lay your plans before God for His approval and guidance, His way is good!
