20 A man’s belly shall be satisfied with the fruit of his mouth; and with the increase of his lips shall he be filled.
Pro 18:20 God will bless us and fill us according to what our lips utter. so speak of good things to cone always so that He will bless the work of your hands.
Adam did not know how to speak negligently until he disobeyed God by eating the forbidden fruit. God knows we cannot handle our own life so He disallowed the forbidden fruit of good and evil.
Adam did not how to speak evil but he knows only how to bless before the fall. God did not want Adam to disobey because He wants him to rule the earth and obey and fellowship with Him. He knows man will be evil if he makes his own choice and will.
Today you can see how evil is the earth! God had to find a better way to have dominion over the earth. Without satan’s knowledge, He sent His Son Jesus to live on this earth to be crucified grotesquely so He could redeem us as it was a perfect sacrifice. So surrender to God and listen to His voice so you will make the right choice in life. God bless all of you.
