To make public our religious affiliation can have its pros and cons.
When others know that we are Christians, they will certainly expect more from us, especially in the areas of kindness and charity.
And when we are not kind or charitable, then we are criticised for not being a "good" Christian.
On the other hand, when others are edified by our behaviour and attitude as Christians, they may wonder and may even be curious to know what we believe in.
In the gospel, when the people of that Samaritan village did not welcome Jesus and His disciples, James and John wanted them to be punished.
But Jesus turned and rebuked them and they went off to another village. Jesus showed forgiveness and compassion.
Jesus practised what He preached, and He also expected His disciples to practise what He preached.
When we follow the teachings of Jesus, especially in the areas of kindness and forgiveness, then others would certainly want to know what is it that we believe in.
Christian means to be another Christ. Let us be Christ to others and then they will want to know what and who we believe in
