The concept of the Trinity is about understanding that God is made up of three parts: the Father, the Son, and the Holy Spirit. Even though there are three parts, they are not different gods; instead, they work together as one single God. This means that when we think about God, we can think of Him as a loving Father, Jesus as His Son who came to save us, and the Holy Spirit as the presence of God that is always with us. So, no matter where we are, we are never alone because God is always by our side.
