I personally take great comfort in Romans 8:26-28:
“And the Holy Spirit helps us in our weakness. For example, we don’t know what God wants us to pray for. But the Holy Spirit prays for us with groanings that cannot be expressed in words. And the Father who knows all hearts knows what the Spirit is saying, for the Spirit pleads for us believers in harmony with God’s own will. And we know that God causes everything to work together for the good of those who love God and are called according to his purpose for them.” (NLT)
So, whether we realize it or not, when we pray, the Spirit interprets our prayers according to God’s will. We are all praying for the same thing, regardless of what we think we are praying for.
