Tzadik means righteous, man who is right and just or a man who is completely devoted to the service of God. The completely "righteous one" can only be God. Tzelem begins with the same letter and refers to God's image in man. Tzadik also stands for number 90 which means total consciousness.
Christian Perspective
We are indebted to the Jews for God's inspired revelation dealing with the creation and fall of mankind. God created man in the beginning giving him a participation in God's life, goodness, truth, beauty, justice, power, wisdom and glory. He was created righteous. But, as we know, man rebelled against God and fell into the darkness of death, error, falsehood, ugliness, injustice and powerlessness. Man became unrighteous.
But God in his mercy prepared the people of Israel to accept his mercy by giving them a way of life which began to lead them back into God's life and friendship. He gave them the Law or Torah with the promise of a Savior to establish the right way between man and God. Paul has well written, "But now the righteousness of God has been manifested apart from the law, though testified to by the law and prophets, the righteousness of God through faith in Jesus Christ for all who believe." (Rm 3:21-22) St. Paul goes on to say that all have sinned and are deprived of the glory of God and that we are justified by faith and grace brought about by the sacrificial expiation of God's Son.
The personal question is: Who do you believe Jesus Christ is? Is a prophet or merely a holy human teacher or is he truly God in the form of man?

Kuf begins the work Kadosh (holy), Karban (sacrifice) and kof (monkey).
Only God is holy, or perfect and separate from his creation, "Holy, holy, holy is the LORD of hosts!" ... "All the earth is filled with his glory!" (Is 6:3) Man must strive for holiness to approach God. Sacrifice refers to animal sacrifice as practiced about 2,000 years ago by the Jews in the temple of Jerusalem but since the destruction of the temple 70 A.D., animal sacrifices have been abandoned. Now, to the Jews, sacrifice means to abandon earthly desires that do not lead to God. The reference to monkey indicates man's vanity and false imitation of this world.
Christian Perspective
Jesus declares in Matthew 5 that holiness goes beyond external obedience to the commandments as follows:
"Do not think that I have come to abolish the law or the prophets. I have come not to abolish but to fulfill."

You have heard it said:
"'You shall not kill; and whoever kills will be liable to judgment But I say to you, whoever is angry with his brother will be liable to judgment ...."
"'You shall not commit adultery.' but I say to you, everyone who looks at a woman with lust has already committed adultery with her in his heart."
"'Whoever divorces his wife must give her a bill of divorce.' But I say to you, whoever divorces his wife (unless the marriage is unlawful) causes her to commit adultery, and whoever marries a divorced woman commits adultery."
"'An eye for an eye and a tooth for a tooth.' But I say to you, offer no resistance to one who is evil. When someone strikes you on (your) right cheek, turn the other one to him as well."
"'You shall love your neighbor and hate your enemy.' But I say to you, love your enemies, and pray for those who persecute you, that you may be children of your heavenly Father, for he makes his sun rise on the bad and the good, and causes rain to fall on the just and the unjust."
