I agree with your comments, however, I personallty feel that there needs to be an appropriate time and/or place for the dialogue. Unfortunately my husband is one who loves to "preach" to anyone at anytime - this has created a number of difficulties for us . He claims he is unable to see that people (adults) are not interested ( and often disturbed with his words) and that he feels the need to make reference to the bible and passages in most conversations - it doesn’t matter if it is a social event or a church group.
If we all made contributions, big or small, with acts of kindness, giving etc, we would be living examples of Christ.
