Intercessory prayer is to intercede on behalf of others. They can be an acquaintance or total strangers. Have you ever felt a burden on you to pray for someone? Sometimes you don’t have a clue as to what to pray for but the Holy Spirit prompts you to pray at a specific time for someone or a group of people. Likewise, the Spirit helps us in our weakness. For we do not know what to pray for as we ought, but the Spirit himself intercedes for us with groanings too deep for words[Romans 8:26
