When I am asked to intercede for people in prayer, I usually pray in Hebrew. I recently had someone express disappointment in this practice. “I don’t understand what you are praying,” they exclaimed. My response was “good!” In reality, I was confused by their desire to understand what I was praying.
The role of an intercessor is to aid someone else in opening their heart to HaShem. This can take several forms, one of which is for the intercessor to try to read what is in the heart of the intercessee and present it to HaShem. This is a good and valid practice, except that intercessors sometimes make mistakes and read the intercessee incorrectly. Even when the intercessor gets the ‘read’ right, there are other problems. The tendency is for people desiring prayer to focus on the intercessor and what they are praying. Instead, they should be focusing on HaShem and opening their own heart to Him. The words of the intercessor can be very distracting whether they are in error or even if they are right on. The energy, however slight, a person expends in concentrating on the intercessor, is energy they are taking away from concentrating on HaShem.
When I pray in Hebrew for others, I try with all my heart to help them open their Ruakh (soul) to HaShem. If they do not understand what I am saying while I pray for them, so much the better. Truly, this is the advantage in praying in tongues also. The point is concentrate on HaShem, not the intercessor. When you pray with an intercessor, let them lead you in opening your heart to HaShem. Don’t worry about what they are saying. Whether they are praying in Hebrew, in tongues, or whatever, focus on HaShem. This is time to concentrate more fully on HaShem than you otherwise do. Keeping this in mind can help your spiritual life take a step forward.
