What does the Bible say about comfort in Christ?

Isaiah 40:1-2 expresses God's desire to comfort His people, reminding them that through the gospel of salvation in Christ, they find true solace. The message of comfort is essential because all humanity is born into sin, but through faith in the Lord Jesus Christ, believers experience peace with God. For those who are elect, comfort is also intended for them when they eventually come to faith. Therefore, it's vital that preachers convey this comfort through the proclamation of the gospel, alleviating the burdens of believers who are weary from the battles against sin, the world, and the devil.
