We will know a tree by the fruit it produces. A mango tree will produce mangoes. A melon plant will produce melons. In a similar way, we know the parents through the children. The children copy and mimic what the parents are. Our works will also determine who is our Father. When we perform works of God, people will know that we have God in us, and that we are children of God. So that when people see the good works in us, they give glory to God. We are baptized Christians and we have received this permanent seal to be living witnesses with our faith. So that when people see how we act, how we behave, how we love, they will know that God exists, that we are children of God.

The world may hate us, ridicule us and persecute us for not conforming with the world and all its allurements, but the Holy Spirit will help us endure and remain steadfast in our faith. That is why only faith can produce these good works that Christ is referring to in the Gospel. By these works of faith, people will know if God is present or not.
