Preaching the gospel is the responsibility of all Christian without exception. Many Christians have not been engaged in preaching the gospel, as it was found in grade X students at a Christian school in Tomohon. The fall into sin makes humans lose the ability to live pleasing and obedient to God's commands thoroughly, but God does not throw away the work of His hands. The human image is restored in the process of redemption when the Holy Spirit regenerates a person and continues to renew the image of God broken by sin through the discipleship process. Christian education is born from a great commission, so it must direct students to become disciples of Christ. This writing was done through a descriptive qualitative study to study ICT subjects as a tool for students to preach the gospel. The study results show that ICT subjects and the role of the teacher can direct the engagement of students to integrate faith and knowledge in preaching the gospel. It is suggested that the teacher provide a place for students to reflect, so problems and results of handling can be identified.
