Explain the significance of Jesus choosing 12 disciples, how Christians should respond to childlessness, and lessons from the call of the first disciples.

1. Reasons why Jesus chose 12 disciples: Jesus chose 12 disciples primarily to symbolize the restoration of the twelve tribes of Israel and to establish the foundation of his new covenant community, the Church. They were chosen to be his closest companions and eyewitnesses to his ministry, teachings, miracles, death, and resurrection. He also selected them to be trained as apostles, giving them authority to preach the Gospel, heal the sick, and cast out demons, thereby extending his mission after his ascension. 2. Ways in which Christians should respond to childlessness: Christians facing childlessness should respond with prayer and faith, trusting in God's sovereign plan and seeking His comfort and guidance. They can explore medical options if desired, and consider adoption or fostering as alternative ways to build a family. It is important to seek support from their church community and other believers, and to find fulfillment in serving God and others through various ministries, recognizing that God's purpose for their lives extends beyond biological parenthood. 3. Reasons Christians learn from the call of the 1st disciples: Christians learn from the call of the first disciples the importance of immediate obedience to Jesus's call, as they left their livelihoods without hesitation. It teaches the principle of sacrifice, demonstrating a willingness to give up worldly comforts and pursuits to follow Christ. The call highlights that Jesus chooses ordinary people for extraordinary purposes, emphasizing that God can use anyone. It also underscores the mission of evangelism, as Jesus called them to be "fishers of men," and the value of discipleship through close fellowship and learning from Jesus.
