This should be a question that we always ask ourselves. After all, “God is love” - [1 John 4:8]. However, it is difficult to discern in many cases and it should not be a question taken lightly. Many times what seems like the most loving action is actually not.
Supporting what others do is a common problem. Supporting someone and supporting their actions are two separate things. Supporting someone’s action that actually harms them is not a loving act at all. Supporting their action gives the person a false notion that the action is good, which in many cases can put their soul in danger.
Many people see supporting someone’s actions as a loving act, but in most cases it is actually a selfish act. We do not want to say or do something that brings division or tension. It is easier to just go with the flow. But, that is not what we are called to do as Christians. We are called to love, even when it is difficult or intensely painful. Just look at Jesus on the Cross.
