It is good that thou shouldest take hold of this; yea, also from this withdraw not thine hand: for he that feareth God shall come forth of them all. (19) Wisdom strengtheneth the wise more than ten mighty men which are in the city. (20) For there is not a just man upon earth, that doeth good, and sinneth not.
By a just man, we may suppose is meant a justified believer in Christ. And of such John the Apostle speaks, when declaring God's faithfulness and justice, to forgive them their sins, 1 John 1:9. Even those are yet exposed to infirmities. It is only among the spirits of just men made perfect, that we are to expect sinless perfection. How endeared in this point of view is Christ, and his atoning blood! 1 John 2:1-2.
