As Christians we all know (most of us do) to love one another. This was so important to Jesus that it was one of the last things He commanded to His Disciples. This sounds easy enough, but what does it look like? It depends on how you view the word love. If love is a verb to you then it is an action, and as you put it into action people are then left feeling loved and therefore comforted, and encouraged.
So how does Love, Comfort, and Encouragement go together? Comforting and encouraging someone are action done as a result of being motivated by love, and if we are called to "love one another" then it also means we are likewise called to comfort and encourage one another. These 3 words are inseparable, for an act done out of love to someone is almost always a comfort and an encouragement to that person.
2nd Corinthians 1:3,4 says,
3 Blessed be the God and Father of our Lord Jesus Christ, the Father of mercies and God of all comfort, 4 who comforts us in all our tribulation, that we may be able to comfort those who are in any trouble, with the comfort with which we ourselves are comforted by God.
We are called to love as He loves us, comfort as He comforts us, and encourage as He encourages us! God created us to have a relationship with one another. God comforts us in the storms of life, and often times He uses us (His people) as the vessel to accomplish this. The question is, Are you available to Him? Are you a vessel He can use?
If we love, comfort, and encourage one another then we can make sure not only us, but our brothers and sisters in Christ ARE vessels that can be useful to God. Without the love, comfort, and encouragement of others in the faith, we are left alone and we can grow weaker in our walk with Christ.
1 Thessalonians 3:1-3 says,
1 Therefore, when we could no longer endure it, we thought it good to be left in Athens alone, 2 and sent Timothy, our brother and minister of God, and our fellow laborer in the gospel of Christ, to establish you and encourage you concerning your faith, 3 that no one should be shaken by these afflictions; for you yourselves know that we are appointed to this.
Paul knew the church in Thessaloniki was in a lot of affliction, so he sent Timothy to them to encourage them. Looking at this in a more modern light, sometimes it takes someone to come in an encourage the church. Today many churches will have a guest preacher come in for a revival. Although the focus is placed usually on winning the lost, a good by-product of the revival is it encourages the church.
