Human beings are capable of doing the right thing because God is just. God's rational nature is important for another reason: it means that God is not unfaithful to God's promises. If God were unreliable and capricious human beings could never know what was true and what was not, what was good and what was bad, what was right and what was wrong. Because God is rational God has created a rationally ordered universe. God has gifted human beings with the capacity to reason and to gain insight into the rational order. Christians are therefore able to believe that there is a truth in any given situation and that truth is accessible, at least in part, to human beings through the use of their reason.   God can be trusted to honour the promises made to human beings. Human beings, as images of God are called to be just, ensuring that God's deepest desires for humankind and the world are realized.

Issues of sexuality and intimacy are closely tied to issues of power and justice (Ferder & Heagle, 2007). When channelled in life-giving ways, sexuality contributes to human flourishing, joy and the sense of belonging for which each of us yearns. In this way, healthy sexual relations overcome distortions of power, seek equality and mutuality, and are visible signs of the Good News preached by Jesus. Good relationships set us free. However, the freedom such relationships give is not a freedom to do as we please, a freedom from all obstacles to our own desires. Rather, by restricting our freedom in a certain sense, we are liberated to take responsibility for our own and others flourishing. Good relationships help us to truly taste the goodness of life.
