Of old it had been said: "Love thy neighbour, and hate thine enemy";[529] but the Lord now taught: "Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you." This was a new doctrine. Never before had Israel been required to love their foes. Friendship for enemies had found no place in the Mosaic code: indeed the people had grown to look upon Israel's enemies as God's enemies; and now Jesus required that tolerance, mercy, and even love be meted out to such! He supplemented the requirement by an explanation--through the course indicated by Him men may become children of God, like unto their Heavenly Father to the extent of their obedience; for the Father is kind, long-suffering and tolerant, causing His sun to shine on the evil and on the good, and sending rain for the sustenance of both just and unjust.[530] And further, what excellence has the man who gives only as he receives, acknowledges only those who salute him with respect, loves only as he is loved? Even the publicans[531] did that much. Of the disciples of Christ much more was expected. The admonition closing this division of the discourse is an effective and comprehensive summary of all that had preceded: "_Be ye therefore perfect, even as your Father which is in heaven is perfect._"[532] SINCERITY OF PURPOSE.[533] In the matter of alms-giving the Master warned against, and inferentially denounced, ostentation and hypocritical display. To give to the needy is praiseworthy; but to give for the purpose of winning the praise of men is rank hypocrisy. The tossing of alms to a beggar, the pouring of offerings into the temple treasure chests, to be seen of men,[534] and similar displays of affected liberality, were fashionable among certain classes in the time of Christ; and the same spirit is manifest today. Some there be now who cause a trumpet to be sounded, through the columns of the press perchance, or by other means of publicity, to call attention to their giving, that they may have glory of men--to win political favor, to increase their trade or influence, to get what in their estimation is worth more than that from which they part. With logical incisiveness the Master demonstrated that such givers have their reward. They have received what they bid for; what more can such men demand or consistently expect? _"But" said the Lord, "when thou doest alms, let not thy left hand know what thy right hand doeth: That thine alms may be in secret: and thy Father which seeth in secret himself shall reward thee openly!"_
