Romans 8: 26 answers: “The spirit also joins in with help for our weakness; for the problem of what we should pray for as we need to we do not know, but the spirit itself pleads for us with groanings unuttered. ”
فإننا لا نعلم ما يجب ان نصلي من اجله عند حاجتنا الى الصلاة ،‏ إلا ان الروح نفسه يشفع لنا بأنّات لم يُنطق بها » .‏
