Jesus modelled and preached good works to those under Law when He rebuked the Pharisees in Matthew 23:23: "Woe to you, scribes and Pharisees, hypocrites! For you pay
tithe of mint and anise and cummin, and have neglected the weightier
matters of the law: justice and mercy and faith. These you ought to have
done, without leaving the others undone." The Pharisees were preoccupied with maintaining a squeaky-clean image and embraced burdensome traditions to appear pious but neglected the unclean conditions of their hearts. They were hypocrites to put greater emphasis on little things others could see rather than addressing their inner wickedness. Jesus pronounced woe upon them for their hypocrisy, and God forbid we who have been cleansed within by the grace of God and rendered righteous should have lives marked with sloth, selfishness and avoidance of doing good. On the night Jesus was betrayed He humbled Himself and embraced the role of a servant of all by washing the disciple's feet as an example we should follow, for a servant is not above his Master.
When the Jews asked Jesus how to do the works of God John 6:29 says, "Jesus
answered and said to them, "This is the work of God, that
you believe in Him whom He sent." Faith in God is a good work we ought to do, and this leads to embracing a primary purpose of our salvation by the Gospel: to do good works! It is written of born-again Christians in Ephesians 2:10, "For
we are His workmanship, created in Christ Jesus for good works, which God
prepared beforehand that we should walk in them." Anyone who is excited about the place Jesus is preparing for us in heaven ought also to be delighted to do the good works God has already prepared beforehand for us to walk in. During the Sermon on the Mount Jesus taught His disciples in Matthew 5:14-16: "You are the light of the world. A city that
is set on a hill cannot be hidden. 15 Nor do they light a lamp and put it under a
basket, but on a lampstand, and it gives light to all who are in the
house. 16 Let your light so shine before men, that they may see your good
works and glorify your Father in heaven." The purpose of lighting a lamp is to give light to everyone in the house, and the purpose for the salvation of lost sinners is do all that Jesus commands us so God will be glorified through the good works of His people: to love and forgive one another, repent of our sin, deny ourselves, take up our cross, and obediently follow Jesus. The commands of Christ are not burdensome, for He has provided the indwelling Holy Spirit Who helps us to know and do God's will.
The doctrine of grace, rather than leading to smug indolence or justifying ourselves, teaches us to embrace our sanctification and good works because we have been justified by faith in Jesus. Paul wrote in Titus 2:11-14: "For
the grace of God that brings salvation has appeared to all men, 12 teaching us that, denying ungodliness and worldly
lusts, we should live soberly, righteously, and godly in the present age, 13 looking for the blessed hope and
glorious appearing of our great God and Savior Jesus Christ, 14 who gave Himself for us, that He might redeem us
from every lawless deed and purify for Himself His own special people,
zealous for good works." We do not work with the hope of gaining favour from God because we already have received grace upon grace. Having been redeemed from death and made alive to God, we are to do the good works of rejecting an ungodly lifestyle and instead living soberly, righteously and godly right now. It is our reasonable service to offer ourselves as living sacrifices to our Saviour who laid down His life for us by looking to Him, walking in fellowship with Him, zealous for good works.
Good works are not a burden we are to place upon others like the hypocritical Pharisees did, but what Jesus leads us to joyfully labour for Him and serve one another as His redeemed. Jesus said in Matthew 11:29-30, "Take My yoke upon you and learn from Me,
for I am gentle and lowly in heart, and you will find rest for your
souls. 30 For My yoke is easy and My burden is light." A yoke was placed upon a team of oxen to do work like pulling a cart, to plough or thresh grain. Jesus bids us come alongside Him, for He will support, help and teach us how to do God's work. In our flesh we are unable to do the first works of God, yet at Jesus' side we are greatly helped and encouraged to do His good works that bring honour and glory to our Saviour Who has redeemed us for His glorious purposes.
