The disciples of the Lord Jesus Christ commanded His disciples to be witnesses in Jerusalem, Judea, Samaria, and the ends of the earth. (Acts 1:8) As Lord Jesus spoke to the disciples in the Sermon on the Mount gives at least three important aspects of being a witness. (Matthew 5:13-16)
Taste and Flavor:
Disciples of the Lord are the salt of the earth. Salt would be one percent of food, but it gives taste and flavor to the food. Once salted, the food cannot be unsalted. Society discovers the meaning and purpose of life when Christians are present. Christians could be a minority in society, but they make a profound impact on progress. For example, Indian culture does not recognize the dignity or rights of individuals, it only prescribes duties according to their caste. The Gospel influence has made individuals to be aware of their rights, self-respect, and aspirations. This salt influence cannot be unsalted.
Guidance:
Disciples are called to shine as light in the dark world. They do not produce light but reflect the Light of the World, the Lord Jesus Christ. (John 8:12) Light is needed to navigate in the world of spiritual darkness. The disciples take the Word, i.e., light to the world. “Your word is a lamp to my feet and a light to my path.” (Psalms 119:105) Since Christians are led by the Word of God, they lead others in the world into truth. Many are unable to make wise decisions, timely decisions. They seek advice, counsel, and suggestions. As worshippers of God who is a wonderful counselor, Christians are natural guides for the groping people around them.
Hope:
The city on the hill cannot be hidden. Christians and the Church are like the city of the Hill offering hope for humanity. In a world filled with fear, violence, despair, devastation, disaster, and diseases, only the Church gives eternal hope. Only hope could sustain and help progress a society or a nation.
Do I add taste and flavor, and offer guidance and Hope to the people around us?
