Sometimes we can care too much what people think about us. This can lead to fear or constantly seeking the approval of others. The problem with this is we will never be satisfied.
In Ezekiel 2, Ezekiel is commissioned to be God’s prophet - to speak God’s word, especially to the rebellious people - the people that are in Exile due to ignoring God. This may result in suffering, opposition and hurt towards Ezekiel. However the Lord commands Ezekiel with the following.
“And you, son of man, do not be afraid of them or their words. Do not be afraid, though briers and thorns are all around you and you live among scorpions. Do not be afraid of what they say or be terrified by them, though they are a rebellious people.” Ezekiel 2:6.
To follow Jesus today means that we care more about what God thinks of us, then what other people do. We are to share the Word of God with everybody, despite the opposition. As they perhaps need God the most. But in regard to not being afraid of opposition to the Word of God - we are not to be cold in our response, but to be speaking the truth in love. Much later in the Bible Jesus even says to his disciples, that if we follow Him, we will need to deny ourselves.
So we must not fear what others think, or fear death. For in Christ there is eternal value which fuels us to endure hardship as we share God’s Word far and wide. God is with us, as we do His Work. Do not be afraid of what comes our way.
