Jesus answered, "Everyone who drinks tis water will be thirsty again, but whoever drinks the water I give him will never thirst. Indeed, the water I give him will become in him a spring of water welling up to eternal life." John 4: 13-14 (New International Version)
The incident of Jesus and the woman at Jacob's well in Samaria describes how people can come to know Jesus as the Messiah Lord, and become His witnesses as well. What begins as a rather cheeky exchange, "Why are you a Jew talking to me a a woman?" ends with "Could he be the Christ?" This woman, who was undoubtedly ashamed of her current situation, was welcomed by Jesus, and led to the point of being confronted as to who He is.
The dialogue between the woman and Jesus takes man turns. The water gives is not must for sustenance, but also for eternal life. The worship God requires is not defined by place, but rather y the attitude of the heart. Overall , it is the Spirit who works in and through believers for transformation. Even in ensuing dialogue with disciples, Jesus reminds them that "My food is to do the will of Him who sent me and to finish His work."
Building relationships is the key to revealing Christ to the world. It takes time, and there is no guarantee of success (although there never was). However, when we "invest" ourselves in others, and reveal God's love to them, then we are also modeling how Jesus has impacted my life. Expressing our faith in worship is not so much, then, about the "how" of what we do, but rather the heart that has brought us into an attitude of praising the Lord.
