More knowledgeable Christians should never mock or disdain weaker believers, nor should they become stumblingstones toward these brethren.
People's motives in serving Christ vary from pure to sinful. However, other men’s motives should not rob us of the joy of Jesus Christ being preached.
Covetousness has often moved men to violence that they might not have otherwise been inclined to do. For instance, wicked king Ahab had a strong desire to obtain a vineyard belonging to Naboth (1 Kings 21:1-4). When Naboth refused to sell the vineyard, Ahab returned to his house to mourn. When Jezebel saw her husband’s grief, she created a plan to take the vineyard by force (1 Kings 21:5-16). This principle is not limited to Ahab and Jezebel but has unfortunately been the historical motive for many acts of violence. When men cannot fulfil the lusts of their flesh in a righteous manner, they simply resort to other means which often includes violence.
