Romans 15:30

Now I beseech you, brethren, by our Lord Jesus Christ, and by the love of the Spirit, that ye strive together with me in your prayers to God for me [Paul appeals to no natural love such as is provoked by environment, propinquity, social or fleshly ties, but to a love induced by the Spirit of God toward one whose face they had never seen. As Christ has power over you, and the Spirit prompts love within you, pray with me and for me. The word "strive" suggests the force of opposing spiritual powers which resist the accomplishment of the things prayed for, and the necessity of ardent prayer to overcome it. The prayer was granted, but by other means than those praying anticipated. With Paul position raised no presumption: neither visions, revelations, miraculous gifts, inspiration nor apostleship lifted him above praying for their prayers. "Spiritual beggary," says Trapp, "is the hardest and richest of all trades. Learn with Paul to beg prayer with all earnestness. 'Pray for me, I say; pray for me, I say,' quoth Father Latimer. 'Pray for me, pray for me, for God's sake pray for me,' said blessed Bradford"];
