Say to the righteous that it shall be well with them, for they shall eat the fruit of their deeds. - Isaiah 3:10
Whosoever that is in the good book of the Lord cannot be broken and ridiculed to scorn while the Lord lives. This speaks to why God is incurably passionate about the righteous. The life of the righteous is an encyclopedia of testimonies of triumphs over trials and afflictions. The Bible says that, "Many are the afflictions of the righteous but the Lord delivers him out of them all (Psalm 34:19). Hence, deliverance is the bread of the righteous, because the Lord will not allow him to suffer reproach and cause His name to be defamed.
The well-being of the righteous is a spiritual driven force that makes God to keep an eagle-eye on them and never to leave them high and dry in trying times. When the Bible says, "Say unto the righteous it shall be well with him", God was actually saying that GOODNEWS will not depart from the habitation of the righteous. The Lord also meant that GOOD HEALTH is the lot of the righteous. Hence, God will not leave him to suffer the horror of affliction of his soul.
And to also wipe away the story of failure of the righteous, the well being of the righteous also means that the righteous will enjoy GOOD SUCCESS. Hence, every examination you face as a righteous fellow will never turn out to become the report of defeat and failure. God wants you to succeed, prosper, excel. That's why He has a word for you, saying, "It is well with you". Hence, I pray every trial of your faith shall yield the harvest of testimonies and breakthroughs in Jesus name.
