The main issue here is the “mystery of Freedom”. The two main keys to this mystery are The Mind of God and the human mind.
Obviously we only have the capacity to use the human mind, which is very limited and imperfect. To have access to God’s Mind the only way is through our Blessed Lord Jesus, and most likely will be the only way until we die. In the meantime the best we can do to understand the ‘mystery of freedom’ is to dive into the Holy Scriptures and to have a deep relationship/close friendship with Jesus in prayer and the Sacraments. After we do this it would be easier to understand how God sees things from a perspective of ‘eternity,’ He sees and knows all things at once. We can only see and know things in steps, in segments of time and space. God can do anything He wants with any reality. In Love, according to His revelation, He decided to respect our freedom. He will not have a direct intervention in our live unless we “open the door” and let Him in.
Revelation also tells us that prayer changes things; not things in the eternal realm, but things in the temporal realm. In prayer and love we can make changes all throughout history, from the fall of Adam and Eve to the Last Judgement. What every man does affects every one else. Our vocation now is to “rule the earth” (by being good stewards) according to God’s will; we can still change things by the grace of God, through Faith, Hope and Love.
After the last judgment, we will not be able to make the slightest change, because there will be no more Faith or Hope, only love. There will be no more ‘time’, since any change requires time. We will be in eternity…we will see everything at once… we will know everything at once… we will see God ‘face to face’… and we will know Him as He knows us… and, of course we cannot understand this now… but if we remain in Jesus we will see everything clearly when the times comes (or when it may go away).
Yet another key to unlocking the mystery of prayer is to understand that the most important element of a life of prayer is “To be at Home.” The parable of “The Prodigal Son” comes to mind here. “To be at Home” means to “live in the same house” where the Father shares everything with his children. There is no need to ask for things every day, although that is welcomed. The family shares everything in common and everyone’s needs are met. Thoughts come and go… feelings are up and down… projects and plans succeed and fail… but the Father is always watching out for His children’s every need… always with the same love and tender care. Although, sometimes He can be tough… but always for the sake of preserving the integrity of His children and the unity of the family. In conclusion, in order to live a life of prayer only one thing is essential: TO LIVE IN THE FATHER’S HOUSE… HE will provide everything else. To leave the House would mean cut-off closeness… cut-off communication and may lead to disaster and death.
