“Why is encouragement emphasized in the Bible? Primarily because encouragement is necessary to our walk of faith.
Jesus told His followers, “In this world you will have trouble. But take heart! I have overcome the world” (John 16:33b). Jesus did not shy from telling His followers about the troubles they would face. In fact, He told them the world would hate them (John 15:18-21; see also Matthew 10:22-23 and 2 Corinthians 2:15-16). But Jesus’ grim forecast was tempered with cheer; He followed His prediction of trouble with a sparkling word of encouragement: He has overcome the world. Jesus is greater than any trouble we face.
Without encouragement, hardship becomes meaningless, and our will to go on wanes. The prophet Elijah struggled with discouragement (1 Kings 19:3-10), and so do we. It is important to remember that “our struggle is not against flesh and blood, but against . . . the powers of this dark world and against the spiritual forces of evil in the heavenly realms” (Ephesians 6:12). This truth makes encouragement all the more important. It is not just that we face the world’s displeasure; we are caught in the crosshairs of a spiritual battle. When we are encouraged in Christ, we have strength to put on our spiritual armor and remain steadfast (see Ephesians 6:10-18).
Even in places where Christians do not experience overt persecution or hatred, we all know that life can be difficult. Discouragement is not an uncommon human experience. At times, recognizing that there is meaning in the seemingly inconsequential things we do seems next to impossible. We may want to give up. Yet He who calls us is faithful, and He gives us the power to be faithful, too (1 Corinthians 1:9).” Gotquestions.org
