Lifestyle and Behaviour Choices


How can a study of the Jesus’ life and the Apostle’s Letters help us determine how to make reasonable choices in behaviour and lifestyle? How can we reflect God’s grace and still give the right message about sin?


The Western world has been very heavily influenced by Christianity and so there is a traditional foundation concerning how life is to be lived. This foundation, however, has been greatly eroded in the last 50 years and for young people today there is no uniform conception of what is right or what is wrong or how we should live our lives. To some extent the motto now is that if we can do something then we should, and there is great resistance to any critique of these lifestyle choices because the foundation for such critiques has been washed away. As our students venture into this world and into a huge array of lifestyle options, they need more than a set of rules. They need the truth, the purpose, the meaning that lies beneath the commands, and ultimately they need the one who gave the commands and who calls them to a higher goal then simply fulfilling their desires.
In Genesis 1 we are told we were created in the image of God, to be like God. So, the question is, what is God like? Leading to, what are we meant to be like? The answer to both questions is found in the one person, Jesus Christ. In the early Church the question of the relationship between Jesus as God and Jesus as a man was hotly debated. It was not until the Council of Chalcedon that the final answer was given, that Jesus was, at the same time, and not by way of mixture, both fully God and fully human, two natures in one person. The importance of the debate centred around the function of Jesus. If we were to truly know God and be brought to God, then we needed someone to bridge the infinite gap between God and ourselves. Only God could do this. So it is only as Jesus is truly God that in him we both see and meet with God, (John 1:1-18). In the same way if Jesus was to take our place on the cross, then he must be truly us, Hebrews 2:10-18. He had to be fully human. As such, Jesus both reveals what God is like and what we are meant to be like, and so to look at Jesus is to look at God’s will for our lives and to see in practice how the mercy and holiness of God relate to each other. Following Jesus, the New Testament is written by the inspiration of the Holy Spirit and is an application to all areas of life of the revelation God had given to us in Jesus. It thus extends that revelation to areas not covered in the Gospels. Jesus also acts as the key that unlocks the meaning of the Old Testament, and so unifies all of God’s revelation by allowing us to see past the immediate context of the OT to the deeper principles which are timeless.
***Note: This unit deals more with personal lifestyle choices, rather then the larger ethical issues which are dealt with in the unit Ethics, Morality and Values. See Ideas/Strategies for Lessons for suggestions.

Key Concepts

  • God created us in his image, in seeking to be like God we become ourselves and fulfill our destiny
  • Jesus shows both what God is like and what we should be like
  • The NT is the application of the Gospel, Jesus, to all of life
  • The OT is understood in the light of Jesus
  • The Ten Commandments stand as a summary of how God wants us to live, which is exemplified in Jesus
  • Jesus sent the Holy Spirit so that we could be like him
  • We are called to me Moral, and all of life comes under God’s critique, as opposed to Relativism which is the only  real option once you ignore God e.g. secular humanism, post-modernism
  • We live in a world where we worship the creation, rather than the creator
  • Is sin really so bad? Apart from all of history, how God sees it is seen in the Cross. The death of Jesus reflects our cruelness, God’s grace and the profoundness of our sin in that Jesus had to die in that way to save us and set the universe right.
  • Satan – comes to kill steal and destroy – encourages wrong behaviour, but also suggests that God is a kill joy – Ie. Deception in the garden of Eden “ God told you that you can’t eat from any tree”.
  • The wages of sin is death = our choices have consequences, short term long term, individual and corporate
  • The gift of God is life in Jesus, who came to give us an abundant life
