The motive is Jesus' motive who came that we might have life abundant and eternal. The gospel is the power of God for the salvation of all who believe, but a fragrance of death to those who reject it (it can save or condemn depending on response to it). It is also not a crime to have interest/curiosity in other religions/experiences, even if one is an atheist. The Great Commandment (love) and Commission (gospel) is for all people groups, Africans, rich, poor, cultists, world religions, lawyers, plumbers, etc. The passion of Jesus and Paul was to reach people with the transforming love and power of God. This is life and death. It would be unloving to keep the cure to cancer to oneself. It is unloving to keep the cure for death and hell to oneself. Read the NT and you will see the value of seeking the lost coin, sheep, prodigal son. There is no higher purpose/calling. Those who are not open can still provide fun and fellowship as we beat up and expose the common enemy of the WT that has negatively impacted lives (I don't have to have had an abortion to fight against it; I don't have to have been JW to stand with those who were against an evil empire).
