Colossians 1:10 (NKJV), "that you may walk worthy of the Lord, fully pleasing Him..."
The first 4 books of the New Testament are known as the Gospels. The Gospels reveal the will of God for us. God wants us to have happy, healthy and prosperous lives. The only way this can happen is by removing sin from our lives.
The Gospels also teach us that removing every sin is impossible for us to do on our own. When the disciples asked Jesus in Matthew 19:25, "...Who then can be saved?" Jesus responded in verse 26, "...With men this is impossible, but with God all things are possible."
Sin can not exist before the face of God. When the devil came before God in the book of Job, He was surrounded by angels as a covering (Job 2:1). When Adam and Eve sinned, they hid from the presence of God (Genesis 3:8). Even Cane was permanently hidden from the face of God when he murdered his brother Able (Genesis 4:14).
It has been God's desire since the fall of Adam that we can fellowship with Him face to face. Yet with any sin in us we would be destroyed instantly. I have heard several people over the years say, "I am a good person". The Bible says in Ecclesiastes 7:20, "For there is not a just man on earth who does good and does not sin." This verse is quoted many times in both the Old and the New Testaments. You must understand that it is impossible for us to be good without receiving the gift of righteousness.
In the Old testament the children of God could obtain a form of righteousness through the sacrifice of an innocent animal. The sins of the people were transferred to the animal. This was a temporary solution and had to be done regularly. Jesus was God in the body of a man. God has no sin so He was the ultimate flawless sacrifice. The sacrifice was so perfect and powerful that it paid for all sins committed past, present and future. All we have to do is receive this gift by faith.
The Bible tells us in Hebrews 11:6, "But without faith it is impossible to please Him (God)..." So How do we walk worthy of the Lord? By faith. We simply have to believe that we are perfect because of what Jesus did on the cross. When we receive this gift, God can come face to face with us. This fellowship will break the bondages of sin in your lives. Unhealthy desires will effortlessly fade away and be replaced by healthy ones.
The verse above (Col 1:10) continues on to say, "...being fruitful in every good work and increasing in the knowledge of God." When you know that any sin in your life has been judged by the sacrifice of Jesus, you will become fruitful in deeds and more personal with God. He has judged all of our sins, past, present and future. You no longer have to hide from the presence of God as Adam and Eve did. This will give God an open opportunity to work through you.
