How can we do whatever we do as unto the Lord (Colossians 3:23)?

TL;DR:

Whatever you do—big or small—can become an act of worship when done for God. Focusing on Christ, living with gratitude, and putting off the old self transforms everyday life into a testimony that glorifies Him.

what does the bible say?

When God says that everything we do should be done for the glory of God, it means that God should not be merely a side note in our life but the priority. The Old and New Testaments teach the foundation of our lives—loving God (Deuteronomy 6:5; Matthew 22:37-38). In his letter to believers in Colossae and his first letter to the Corinthians, Paul spoke of this kind of devotion to God pervading our lives (Colossians 3:23; 1 Corinthians 10:31).

Chapter 3 of Colossians describes how to live heartily as unto the Lord. Verse 2 encourages believers to focus on God's kingdom and eternal values, rather than temporary, worldly concerns. Verses 5-9 list eleven negative characteristics to put off as contrasted with the positive characterics listed in verses 12-16 . Verse 17 summarizes by saying "do everything in the name of the Lord Jesus," and verse 23 echoes this principle. When we do everything for the Lord, our lives become a living testimony of His presence, power, and grace in the world.

from the old testament

King Hezekiah was successful by seeking God and acting wholeheartedly in every work he undertook in service of God's Temple (2 Chronicles 31:21). He modeled the type of wholehearted devotion all believers should have.

from the new testament

Paul wrote to believers in Colossae, "Whatever you do, work heartily, as for the Lord and not for men, knowing that from the Lord you will receive the inheritance as your reward. You are serving the Lord Christ" (Colossians 3:23-24). All work, whether secular or sacred, is an opportunity to worship God and glorify Him before others.
In Paul's first letter to believers in Corinth, he discussed not using our Christian freedom to make a brother or sister stumble. He provides this guideline for our behaviors: " So, whether you eat or drink, or whatever you do, do all to the glory of God" (1 Corinthians 10:31). Every action, whether significant or mundane, should be an act of worship and honor to God.
Our thoughts and desires should be focused on heavenly realities instead of earthly distractions (Colossians 3:2).
Whatever we do or say, we are called to do it as a representative of the Lord Jesus, giving thanks through Him to God the Father (Colossians 3:17). By doing this, we become a living testimony to the life-changing power of God.

implications for today

Jesus summarized the foundation of all commands: Love God with all our heart, soul, and mind and love others as ourself (Matthew 22:36-40). The whole "law" hinges on those two commands. This means that we are to submit everything, and every moment to Christ. It's not about creating a spiritual checklist. It's about a leading a life submitted to Christ.

This gives purpose to everything we do. We can work, raise children, take care of our home, lead a Bible study, have friendships, and more as unto the Lord. We do this by seeking to honor and reflect Him in all we do. We do this as we surrender our wills to His in all these areas. We do this by being good stewards of what He has given us and faithfully doing all things for Him, including with our attitudes, habits, thoughts, and actions.

Several things help prepare us to do all things as unto the Lord: prayer, being immersed in God's Word, and fellowship with other believers move our attention back to what matters. They give us perspective and remind us of our purpose in all we do. Our relationship with Christ is not about a set of rules—human minds could never make enough individual rules to cover every possible situation. Instead, a life submitted to Christ will generate a grateful heart and a godly, eternal perspective each day in everything we do. And doing this transforms our lives into testimonies that glorify Him and reflect Him to a world that desperately needs Him.
