1 In the past God spoke to our ancestors through the prophets at many times and in various ways, 2 but in these last days he has spoken to us by his Son,whom he appointed heir of all things, and through whom also he made the universe. 3 The Son is the radiance of God’s glory and the exact representation of his being, sustaining all things by his powerful word. After he had provided purification for sins, he sat down at the right hand of the Majesty in heaven. — Hebrews 1:1-3 NIV
Jesus provided purification for our sins when He hung on a cross. From that cross, He announced that “it is finished”. His work here on earth was completed. God gloriously raised Jesus from the dead and He ascended into heaven. He is there now, at the right hand of the Father, interceding for us.
34 Who then is the one who condemns? No one. Christ Jesus who died—more than that, who was raised to life—is at the right hand of God and is also interceding for us. — Romans 8:34 NIV
There are times in our lives when we become so frustrated or burdened that we do not how or what to pray. Those can be the times that our prayers are the most fervent and the most effective. God, in His great mercy and love for us, has made a way for us to pray at any time in any situation. When we reach the place where we are at a loss as to what to say or pray. the Holy Spirit prays through us and for us.
26 In the same way, the Spirit helps us in our weakness. We do not know what we ought to pray for, but the Spirit himself intercedes for us through wordless groans. 27 And he who searches our hearts knows the mind of the Spirit, because the Spirit intercedes for God’s people in accordance with the will of God. — Romans 8:26,27 NIV
When we are praying and we literally run out of words to say, we should stop and consider this fact: The complete Trinity is involved in every prayer we pray. The Holy Spirit takes our stumbling, bumbling mutterings and groans. He cleans them up and presents them to the Father as Jesus watches and intercedes on our behalf. A simple prayer is sufficient since God already knows what we need. Peter’s prayer “Lord, save Me!” moved Jesus to save him from the angry waves and those three words are still enough to bring salvation.
