We are exhorted in Hebrews 10:22 to draw near to God. This command is not written to unbelievers but to believers! The ground upon which such an exhortation rests is the person of the risen Lord and His finished work upon the cross on which He shed His precious blood. What a High Priest is ours!! What a hope and what a confidence! Yet; as one looks closer at the verse in question; we are exhorted to draw near to God with a true (sincere) heart free from hypocrisy so as to be able to draw near in full assurance (entire confidence) of faith.
Sadly, there are many who through consciences defiled by sin; are not able to draw near to God with a true heart and in full assurance of faith. This sermon is a challenge to such to forsake that which they know to be wrong in their lives so as to be able to exercise a good conscience towards God, holding faith unswerving without which we cannot ever draw near to our God; For, “…without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him” (Heb. 11:6).
