Music is considered as a very effective and even necessary tool for children to learn Jesus' love and the biblical truth, because God has given music an enormous power to mould listeners' character, which could eventually change their life. For last twelve years we have witnessed such transformation happening in the children who participated in this event. Rev. Luis Buch, the initiator of 4/14 Window movement which focuses evangelism on the age group between 4 and 14, also recognizes the need of a more holistic approach to children, which also includes music.

​

"From a missions standpoint, our interest in the 4 to 14 age group is not only because they are the most receptive, but also because as we will see, they are often the most effective agents of mission. Of course, Jesus understood their worth: "I praise you Father, Lord of heaven and earth," He said, "because you have hidden these things from the wise and learned and revealed them to little children. Yes, Father, for this was your good pleasure" (Matthew 11:25-26)." —4/14 Window brochure
