How To Conduct Ourselves Among Unbelievers

The brothers can conduct themselves among unbelievers spiritually in two ways. One way is to avoid quarrels or disputes and be subject to every human creature for God's sake (1 Peter 2:13), so bearing witness in the fact that they are Christians. Another way is to proclaim the word of God openly, when they see that is God's will, calling on their hearers to believe in God almighty, Father, Son, and Holy Spirit, the Creator of all, and in the Son, the Redeemer and Savior, that they may be baptized and become Christians, bucause unlesws a man be born again of water, and the Spirit, he cannot enter the kingdom of God (John 3:5).
