And hope maketh not ashamed; because the love of God is shed abroad in our hearts by the Holy Ghost which is given unto us. Romans 5:5 KJV
The love of God, who is Love, fills us when we receive Jesus as Lord and Savior.
The Holy Ghost brings the character and nature of God into our character and nature. His agape Love floods our being and we become lovers instead of haters, peaceful instead of violent, confident instead of insecure, and led of the Spirit instead of by the flesh.
The Blessed Hope cannot disappoint because He is Love and Love never fails.
