The Bible connects tribulation, The Comforter, comfort, rest, multiplication and the fruit of The Spirit. Christians seem to have been persecuted more in the last few decades. Perhaps we ought to be praying for tribulation.
2 Corinthians 1:3 Blessed be God, even the Father of our Lord Jesus Christ, the Father of mercies, and the God of all comfort; 4 Who comforteth us in all our tribulation, that we may be able to comfort them which are in any trouble, by the comfort wherewith we ourselves are comforted of God.
John 14:16 And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever;
Acts 9:31 Then had the churches rest throughout all Judaea and Galilee and Samaria, and were edified; and walking in the fear of the Lord, and in the comfort of the Holy Ghost, were multiplied.
Romans 5:3 And not only so, but we glory in tribulations also: knowing that tribulation worketh patience; 4 And patience, experience; and experience, hope: 5 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.
Psalms 23:1 The LORD is my shepherd; I shall not want 2 He maketh me to lie down in green pastures: he leadeth me beside the still waters. 3 He restoreth my soul: he leadeth me in the paths of righteousness for his name's sake. 4 Yea, though I walk through the valley of the shadow of death, I will fear no evil: for thou art with me; thy rod and thy staff they comfort me. 5 Thou preparest a table before me in the presence of mine enemies: thou anointest my head with oil; my cup runneth over. 6 Surely goodness and mercy shall follow me all the days of my life: and I will dwell in the house of the LORD for ever.
