Genesis 6:3 And the Lord said, My spirit shall not always strive with man, for that he also is flesh: yet his days shall be an hundred and twenty years. 5 And God saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually.
Again, during the times of the Antediluvians, God provided food and drink for the rebellious, up until the very day of the flood, for as was stated before, there are some basic fundamental mercies that God dispenses to all of humanity, including the stranger within thy gates. This will also be manifested when the seven plagues of Revelation 16 are being poured out. They will not be universal in nature, for then all the inhabitants of earth would be destroyed.
[The Great Controversy pp 628] These plagues are not universal, or the inhabitants of the earth would be wholly cut off…. Just because Cain turned his back on God, it did not mean that he and his offspring would be deprived of the essentials for daily living. Yes, it is true that the natural consequences of his choices and actions will produce a natural curse as time went by, but Cain would have access to food and drink.
God does not starve sinners into submission as the devil would attempt to do in Revelation, chapter 13. Instead, The Lord gives to persons a lot of grace and mercy, even where sin abounds. Thus, God sets the gold standard for the treatment of the strangers within our gates, and it is of critical importance for us Christians to reflect the goodness and character of God, for His character is magnified or reproached by what the professed Christian does or does not do.
Isaiah 43:11 I, even I, am the Lord; and beside me there is no Savior. 12 I have declared, I have saved, and I have shewed, when there was no strange god among you: therefore, you are my witnesses, saith the Lord, that I am God.
May The Lord add His blessing to the study of His word. God bless!
