The Bible Colossians 4: 5- 6 (NIV) Be wise in the way you act toward outsiders, make the most of every opportunity. Let your conversation be always full of grace seasoned with salt so that you may know how to answer everyone.
Christians should not hate unbelievers but they should tolerate them and they should be concerned about their salvation. Furthermore, Christian should not act like unbelievers when we are in their company. As Christians, our main focus should be first the Cross of Christ. That is remembering we were once unbelievers and Jesus gave us the ability to change so, therefore be kind and patient towards unbelievers. Our behavior around unbelievers should make them want what we have. However well sadly to say many Christians cause unbelievers to run away from God. It is imperative to remember that every non-Christian is out of relationship with the Lord. 1 John 3: 10 ESV ( paraphrased) Jesus appeared to take away sin and that Jesus had no sin. Furthermore, the same scripture explained saying no one keeps on sinning who has either seen or known God. The same scripture explains that whoever practices righteousness is righteous, and whoever makes a practice of sinning is of the devil because the devil has been sinning from the beginning. The reason the Son of God appeared was to destroy the works of the devil. Knowing this all Christians must walk in wisdom towards unbelievers. God will give us the right words to say if we ask him. God will guide us. We are only spiritual farmers. Some of us plant a seed and some Christians water the seed, however, God is the one who brings the increase. God causes the seed to grow. The Apostle Paul address the Corinthians in First Corinthians chapter 3:5-7 saying “After all, who is Apollos? Who is Paul? We are only God’s servant through whom you believed the Good News. Each of us did the work the Lord gave us. I planted the seed in your hearts, and Apollos watered it, but it was God who made it grow. It’s not important who does the planting, or who does the watering. What’s important is that God makes the seed grow.”
