The origin of the word “intercession” comes from the Latin “cedere” which means “go”, and “inter” that means “between.” When put together, the word “intercede” is formed, wherein “intercession” was derived. Looking at these definitions, we can get the meaning of the word, which is to go in between.
Intercession is often used in prayer. Someone may intercede for someone else in prayer in times of trouble and suffering, or to seek reparation for a mistake. In the Old Testament, Moses interceded for the people of Israel so that God would not punish them for creating the golden molten calf.
In the New Testament, all Christians have one Intercessor, the man Christ Jesus, who mediates between God and man. Ever since He rose again and seated at the right hand of the throne, all He does is to pray and intercede for His people.
