What does the Bible say about symbols in Christianity?

In the New Testament, symbols are not the primary means through which believers express their faith. Christ did not instruct His followers to adopt various symbols; rather, He emphasized the importance of the work done in the heart by the Holy Ghost. For example, circumcision, which was a symbol in the Old Covenant, was deemed unnecessary for true faith in Jesus Christ as articulated by the Apostle Paul. Rather than focusing on physical representations, believers are called to embrace the symbolism given by Christ, such as baptism and the Eucharist, which are rooted in the transformative work of grace in a believer's life.
