Is it ethical to target vulnerable people for conversion?

The Bible commands Christians to share the Gospel with all people (Matthew 28:19). However, Christian ethics strictly prohibits coercion, manipulation, or exploitation in the act of evangelism. Targeting vulnerable individuals—such as the poor, sick, or those experiencing a crisis—is unethical if the purpose is to exploit their desperation by offering material aid (food, money, housing) in exchange for a profession of faith. True Christian evangelism must honor the person's dignity and rely solely on the convicting power of the Holy Spirit and the truth of the Gospel, ensuring that conversion is a free, sincere, and uncoerced choice.
