Isaiah 59:1 Behold, the Lord’s hand is not shortened, that it cannot save; nor His ear heavy, that it cannot hear.
Never think for one second that God does not have the power to destroy evil, take out Satan, remove sin and everything else this instant! It is His choice not to do this right now…
If God removed it all or left us to fend for ourselves after one last stand then we would be nothing. It is God alone that upholds the heavens so that we may continue to live on planet earth.
God always hears our prayers and always answers in the manner that is best for us. Let us trust Him and believe Him and wait with patience as He has asked.
