He has told you men what is good and what it is the Lord requires of you: Only to act justly, to love faithfulness, and to walk humbly with your God.Micah 6:8(HCSB)
It was through the perfect Law of Moses that God showed mankind what is good and acceptable in His sight. Mankind was to reverence the Lord and to walk in faithful obedience to Him, to love Him and to humbly serve Him with all their heart and soul. But the sin nature in man that was imputed to the human race when Adam disobeyed God, caused man to walk in enmity towards God, in disobedience, and to place self on the throne of his life, instead of the Lord.
But the Law and sacrifices given to Moses were copies of heavenly things and foreshadowed God's better Sacrifice - for the Law was only a shadow of the good things to come, and not the actual form of those realities. The Law could never perfect the worshipers and provide perfect cleansing for those who came to worship God year after year. The good sacrifices of the Mosaic Law foreshadowed the Lord Christ Jesus, Who is the better Sacrifice. The Law of Moses was to prepare the way for the gospel of grace; it was a schoolmaster to point us to Christ.
It is only those that have trusted Christ as Saviour who are able to act justly and be merciful and walk humbly before their God, for only those that are born from above have been endowed with the new-life in Christ, the godly nature of Christ Jesus. Only believers are imputed with His righteousness, which alone can act justly, love faithfulness, and walk humbly before God.
If a born-again believer chooses to live their life from the source of the old sin nature, he will never do that which is pleasing in the sight of God, for only as a believer lives his life from the source of the new- life in Christ is he able, through the power or His Spirit, to the glory of God the Father.
Loving Lord, it is my desire to walk humbly before You all the days of my life. Thank You for sending the Lord Jesus to live a perfect life and die as the perfect sacrifice so that I could be imputed with His perfect righteousness, enabling me, in His power, to walk humbly before You. In Jesus' name, AMEN.
