In the same way, the Ruach helps in our weakness. For we do not know how to pray as we should, but the Ruach Himself intercedes for us with groans too deep for words. And He who searches the hearts knows the mind of the Ruach, because He intercedes for the kedoshim according to the will of God” (Romans 8:26-27).

What does intercession mean to you and why would you intercede on another’s behalf, or need another to interceded for you? Instead of looking to the dictionary for the meaning, it may be more helpful, in this context, to look at biblical examples of someone acting as an intercessor. 

Abraham interceded for Sodom and Gomorrah before God destroyed it. Abraham began appealing to God for the sake of fifty righteous people living in those cities, with his last plea being, “Please, let not my Lord be angry, so I may speak once more. Perhaps ten will be found there?” And He said, “I will not destroy it for the sake of the ten.” (Genesis 18:16-33). Abraham interceded for Abimelech after he took Sarah thinking she was Abraham’s sister. God visited Abimelech in a dream and told him to return Sarah, or he would die. “So now, return the man’s wife, for he is a prophet. And let him pray for you and you will live. But if you do not return her, know that you will surely die—you and all who are yours” (Genesis 20:7). After a seemingly tense meeting between Abraham and Abimelech, we learn that “Abraham prayed to God and God healed Abimelech, his wife and his female slaves so that they could bear children. For Adonai had completely shut up every womb in Abimelech’s household because of Sarah, Abraham’s wife” (Genesis 20:17-18).
