There are issues in which believers will disagree. In such cases, we should understand that we will independently stand before the judgment seat of Christ.
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.
Fear introduced is faith attacked. As such, we should not be partakers of the world’s fears. Instead, we should “sanctify the LORD of hosts himself; and let him be” our fear (Isaiah 8:13). Throughout scripture, the Lord admonished His people not to fear the world. Why? The answer is twofold: (1) the Lord was with them (Genesis 26:24) and (2) fear of the world yields bondage (Proverbs 29:25). This worldly bondage never originates with the Lord (Romans 8:15) for He has given Christians a sound mind (2 Timothy 1:7). We need not fear those who can destroy the body (Matthew 10:28); rather, we ought to say the Lord is our helper, and we will not fear what men will do unto us (Hebrews 13:6).
