Don't Take It Personally
The prophet Samuel was the last judge of Israel. When he was old, the people rejected his sons to be judges over them and wanted a king like the nations around them. This rejection deeply grieved the faithful and uncompromising servant of God. He went to the God of all comfort, Who instructed Samuel to not take personally the rejection. The LORD said to Samuel, "Hearken unto the voice of the people in all that they say unto thee: for they have not rejected thee, but they have rejected Me, that I should not reign over them." (1 Sam 8:7).
In His highly contentious conversation with the Pharisees in John 8, Jesus was insulted twice by the Pharisees (John 8:41, 48). He did not respond to either insult, not defending Himself but rather defending the honor of His Father.
Let us have the mind of Christ as we witness of Him, not responding to personal insults hurled at us while standing firm for the honor of our Lord. Jesus is worthy of all honor (Rev 4:11, Rev 5:12) and we are not worthy of any (Gal 2:20), so why be offended by an insult? If your witness is rejected, don't take it personally; the unbelieving are rejecting Jesus Christ, not you.
