just some passages on the mystery of prayer
from Romans 8
12Therefore, brothers, we have an obligation—but it is not to the sinful nature, to live according to it. 13For if you live according to the sinful nature, you will die; but if by the Spirit you put to death the misdeeds of the body, you will live, 14because those who are led by the Spirit of God are sons of God. 15For you did not receive a spirit that makes you a slave again to fear, but you received the Spirit of sonship.[g] And by him we cry, "Abba,[h] Father." 16The Spirit himself testifies with our spirit that we are God's children. 17Now if we are children, then we are heirs—heirs of God and co-heirs with Christ, if indeed we share in his sufferings in order that we may also share in his glory.
18I consider that our present sufferings are not worth comparing with the glory that will be revealed in us. 19The creation waits in eager expectation for the sons of God to be revealed. 20For the creation was subjected to frustration, not by its own choice, but by the will of the one who subjected it, in hope 21that[i] the creation itself will be liberated from its bondage to decay and brought into the glorious freedom of the children of God.
22We know that the whole creation has been groaning as in the pains of childbirth right up to the present time. 23Not only so, but we ourselves, who have the firstfruits of the Spirit, groan inwardly as we wait eagerly for our adoption as sons, the redemption of our bodies. 24For in this hope we were saved. But hope that is seen is no hope at all. Who hopes for what he already has? 25But if we hope for what we do not yet have, we wait for it patiently.
26In 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 with groans that words cannot express. 27And he who searches our hearts knows the mind of the Spirit, because the Spirit intercedes for the saints in accordance with God's will.
Because you are sons, God sent the Spirit of his Son into our hearts, the Spirit who calls out, "Abba,[a] Father." 7So you are no longer a slave, but a son; and since you are a son, God has made you also an heir.from 1 John
18Dear children, let us not love with words or tongue but with actions and in truth. 19This then is how we know that we belong to the truth, and how we set our hearts at rest in his presence 20whenever our hearts condemn us. For God is greater than our hearts, and he knows everything.
21Dear friends, if our hearts do not condemn us, we have confidence before God 22and receive from him anything we ask, because we obey his commands and do what pleases him. 23And this is his command: to believe in the name of his Son, Jesus Christ, and to love one another as he commanded us. 24Those who obey his commands live in him, and he in them. And this is how we know that he lives in us: We know it by the Spirit he gave us.
