Choice and faith

When we are working with people to look at issues, it seems to be increasingly important for people to maintain a sense of control over decisions made and this is the basis of all good one to one work. Yet when we talk about choosing to become a Christian we use language such as giving over you life to God. This can lead to people seeing faith as something that will have the effect of changing them reguardless of what they think or their part in the process and thus for some becomes a stumbling block.
Do we need to think more about our language in contemporary society and encourage people to see that the choice is theirs and resides with them. They have the choice to change and God will take their loaves and fishes and do with it as S/He will, but that following God and the changes that result are always dependent on our choosing to bring forward the loaves and fishes each day.
