Seek ye the Lord while He may be found, call ye upon Him while He is near.
7 Let the wicked forsake his way and the unrighteous man his thoughts; and let him return unto the Lord, and He will have mercy upon him, and to our God, for He will abundantly pardon.
8 “For My thoughts are not your thoughts, neither are your ways My ways,” saith the Lord.
9 “For as the heavens are higher than the earth, so are My ways higher than your ways and My thoughts than your thoughts.
