Righteousness

Three hundred and six times the word "righteousness" appears in the KJV. The first time is in Genesis 15:6 where Moses says that "...Abraham believed the Lord and it was counted unto him as righteousness." God told Abraham to leave Ur and go into a country that would later be called Israel. His obedience to God's request is the first record of righteousness by faith (Enoch aside).
Revelation 19:11 "righteousness" appears the final time. John writes: "And I saw heaven opened, and behold a white horse; and he that sat upon him [was] called Faithful and True, and in righteousness he doth judge and make war."
In The Revelation the Greek word "dikaiosyne" is used as follows:

1) in a broad sense: state of him who is as he ought to be, righteousness, the condition acceptable to God
a) the doctrine concerning the way in which man may attain a state approved of God
b) integrity, virtue, purity of life, rightness, correctness of thinking feeling, and acting
2) in a narrower sense, justice or the virtue which gives each his due*

In the Hebrew (Genesis 15:6) "tsedaqah" is applied as follows:
1) justice, righteousness
a) righteousness (in government)
1) of judge, ruler, king
2) of law
3) of Davidic king Messiah
b) righteousness (of God's attribute)
c) righteousness (in a case or cause)
d) righteousness, truthfulness
e) righteousness (as ethically right)
f) righteousness (as vindicated), justification, salvation
1) of God
2) prosperity (of people)
g) righteous acts*

That there is harmony of meaning in "righteousness" from first to last in the Bible is obvious. The beautiful thing about righteousness is this: it is a gift from God to those who believe and follow the Christ. Amen,
