The Holy Spirit is often described in the New Testament as the Comforter. (John 14:16, 18; John 16:7) Why? Because I can be comforted knowing that my sins are washed and cleansed in the perfect righteousness of my faithful Saviour Jesus Christ. There is no greater comfort than knowing and believing that. I am eternally secure in Him.
Hope as the fruit of the Spirit is not a wishful thinking kind of thing, but as sure and solid as if it were already obtained. (2 Cor 3:12) As the Psalter puts it: "Hope in the Lord ye waiting saints and He will well provide." That hope is based on the grace and mercy of our Lord and Saviour Jesus Christ Who "is the same yesterday, today, and forever." (Heb 13:8) He does not change (immutable) and He is faithful to His Word.
Peace is the third gift of the Spirit that I constantly need every day. Peace that passes all understanding will help me to cope and not question God's wisdom and plan for my life. I have peace knowing that my heavenly Father is guiding all things for my good (Rom 8:28). Jesus promised His disciples that when He would leave them that He would give them peace. All that we have to do is ask, and that peace can be ours as well.
