and they greatly vary depending on who you talk to.. even though there is basically one body of Christ, one Church, one Bible.
Since in honestly most people have never read the Bible regularly themselves they all thus mostly do rely on what what a Christian is by what the others have told them.
The opinion of what a Christian is varies from one who is an active regular adherent, member of the church, or one who has been baptized by water in a church, or one one who has Christian parents, or one who has a paid up membership in a church.
But still a Christian is not only a person who admits he or she is a sinner, admits that Jesus Christ is God, and he now humbly asks God for personal forgiveness and accepts it too, and next is one who has been born from above, personally regenerated by the Holy spirit of Christ, but he or she is also still one who daily prays, reads the Bible, and practices it as well.
The Christian daily practice includes demonstrating God’s love through us to others, other Christians firstly now as well.
