This might seem shocking to some, but when we conisder prayer, we are not omniscient. By that I mean, there are many times we don't even know what to pray for. Either there are dangers we are not aware of so we don't pray...or there may be ministries God wants to use us in that are incompressible to us so we don't pray...or perhaps our prayer life is skewed to the point we are praying for things that are contrary to God's will and purpose. Jeremiah the prophet found himself in each of these categories...and so do we.
God, in His grace, intervenes and the Spirit prays for us in ways we don't even recognize or understand.
the Holy Spirit helps us with our daily problems and in our praying. For we don't even know what we should pray for nor how to pray as we should, but the Holy Spirit prays for us with such feeling that it cannot be expressed in words. 27 And the Father who knows all hearts knows, of course, what the Spirit is saying as he pleads for us in harmony with God's own will. (Romans 8:26-27 TLB)

Well then...because sovereign, omniscient God prays for us in ways we cannot express, then why pray at all?...just let the Spirit pray for us. This is not how God designed our lives to be lived. He desires our conscious prayer. It testifies to our dependence upon Him and His love for us. God told Jeremiah...and us: “Thus says Yahweh who made the earth, Yahweh who formed it to establish it; Yahweh is His name, 3 ‘Call to Me and I will answer you.” It is through our conscious praying that God's hand is moved. For example, the Spirit inspired James to write this: “5 But if any of you lacks wisdom, let him ask of God, who gives to all generously and without reproach, and it will be given to him. 6 But he must ask in faith, doubting nothing, for the one who doubts is like the surf of the sea, driven and tossed by the wind. 7 For that man ought not to expect that he will receive anything from the Lord, 8 being a double-minded man, unstable in all his ways. (James 1:5-8)

My prayer for you and me this day is this: Lord, we are eternally grateful that You intercede for us when we don't know how or what to pray for, but we are just as grateful that we can come into Your very presence with the concerns we have and know about. May we be more faithful in our personal prayer life. Amen.

Walk with the King today and be a blessing.
