To Work Righteousness, Believe on Jesus' Finished Work

"{A Psalm of David.} LORD, who shall abide in thy tabernacle? who shall dwell in thy holy hill?

2He that walketh uprightly, and worketh righteousness, and speaketh the truth in his heart." ( Psalm 15: 1-2)

What does it mean to work righteousness?

Does it mean that we do righteous things?

Honestly, there is no one on this earth who is righteous in himself, or through anything that he does:

The Psalmist accepted it:

"They are all gone aside, they are all together become filthy: there is none that doeth good, no, not one." (Psalm 14: 3)

King Solomon admitted it:

"If they sin against thee, (for there is no man that sinneth not,) and thou be angry with them, and deliver them to the enemy, so that they carry them away captives unto the land of the enemy, far or near;" (1 Kings 8: 46)

and

"For there is not a just man upon earth, that doeth good, and sinneth not."  (Ecclesiastes 7: 20)

Paul the Apostle affirmed it:

"As it is written, There is none righteous, no, not one:" (Romans 3: 10)

Isaiah the prophet further condemned any righteous works that we can do:

"But we are all as an unclean thing, and all our righteousnesses are as filthy rags; and we all do fade as a leaf; and our iniquities, like the wind, have taken us away." (Isaiah 64: 6)

Under the New Covenant, our work is to believe on Jesus!

"Then said they unto him, What shall we do, that we might work the works of God? 29Jesus answered and said unto them, This is the work of God, that ye believe on him whom he hath sent." (John 6: 28-29)

Does this offend you? Do you find this revelation untrue? Consider what John wrote in his First Epistle:

"For this is the message that ye heard from the beginning, that we should love one another. 12Not as Cain, who was of that wicked one, and slew his brother. And wherefore slew he him? Because his own works were evil, and his brother's righteous" (1 John 3: 11-12)

Now, what work is John referencing? The sacrifices, and Abel's sacrifice relied on the blood of the unblemished lamb.

We have that Perfect Sacrifice today, in Christ Jesus! (1 John 2: 1-2)

The work of cleansing away our sins has been finished forever, through Jesus!

Today, to work righteousness, then, it all comes down to believe on Jesus and His Finished Work.
