A good question to be sure, but how should we show the world that we are Christian? I believe this should be asked in a different way, how are we showing others that we are Christian?
Is it in our words? Our stance on issues? Is it how we feel about others who are not Christian?
Consider the last time you met someone who was not a Christian, what did you do to let that person know you are a follower of Christ? Moreover, did you do anything to make that person feel at ease? Or did you not?
Paul provide us with guidance in how we should act with others, in 2 Timothy we are told, “But reject foolish and ignorant speculation, for you know that it breeds quarreling.” How often do we speculate first, without looking for understanding? He continues, “And a servant of the Lord must not be quarrelsome, but he must be kind to everyone.” Must be kind to everyone, have you been kind to those who you meet? And lastly, he tells us we must be “Able to teach, and forbearing. We must gently reprove those who oppose us, in the hope that God may grant them repentance leading to a knowledge of the truth.” (2 Timothy 2:24 NIV)
What Paul is telling us, what Jesus speaks about in Matthew 5:16,” In the same way, let your light shine before others, so that they may see your good works and give glory to your Father who is in heaven.” Jesus tells us to show to others the work of the Father and the Son within us.
James tells us that we must show that we are followers, he states “Therefore, confess your sins to one another and pray for one another, that you may be healed. The prayer of a righteous person has great power as it is working.” (James 5:16 NIV)
Given what we learn from Jesus, Paul, and James, how are you showing others that you are a Christian? In words alone? Or in your actions with all people that you meet?
