Read Romans 8:26-39
26 In the same way the Spirit also comes to help us, weak as we are. For we do not know how we ought to pray; the Spirit himself pleads with God for us in groans that words cannot express. 27And God, who sees into our hearts, knows what the thought of the Spirit is; because the Spirit pleads with God on behalf of his people and in accordance with his will.
28 We know that in all things God works for good with those who love him,l those whom he has called according to his purpose. 29Those whom God had already chosen he also set apart to become like his Son, so that the Son would be the eldest brother in a large family. 30And so those whom God set apart, he called; and those he called, he put right with himself, and he shared his glory with them.
31 In view of all this, what can we say? If God is for us, who can be against us? 32Certainly not God, who did not even keep back his own Son, but offered him for us all! He gave us his Son—will he not also freely give us all things? 33Who will accuse God’s chosen people? God himself declares them not guilty! 34Who, then, will condemn them? Not Christ Jesus, who died, or rather, who was raised to life and is at the right-hand side of God, pleading with him for us! 35Who, then, can separate us from the love of Christ? Can trouble do it, or hardship or persecution or hunger or poverty or danger or death? 36As the scripture says,
“For your sake we are in danger of death at all times;
we are treated like sheep that are going to be slaughtered.” 37No, in all these things we have complete victory through him who loved us! 38For I am certain that nothing can separate us from his love: neither death nor life, neither angels nor other heavenly rulers or powers, neither the present nor the future, 39neither the world above nor the world below—there is nothing in all creation that will ever be able to separate us from the love of God which is ours through Christ Jesus our Lord.
"The Spirit helps us in our weakness..." (Verse 26)
Paul concludes in verse 37: "In all these things we are more than conquerors..."
From chapter 7:14 Paul speaks about the inner conflict between the flesh and the Spirit. Life in the Spirit produces the character of Christ in us; life in the flesh is more selfish. Paul helps us to understand how God is at work in us, making us more like Jesus.
"For we do not know how we ought to pray; the Spirit himself pleads with God for us in groans that words cannot express."
Sometimes words are not enough to express our hearts to God.
