After understanding, with compelling coherence, some teachings for which multiple interpretations have been given, albeit with lesser coherence, and some even out of context, I have come to the conclusion that it's almost impossible to know what God requires of us without supernatural help.
After all, we are separated from the original information by several millenia and even geographically, and when we often misunderstand ongoing conversations because of semantics and idiosyncrasies, imagine the possibilities of missing the meaning in these extreme situations.
Fortunately, understanding the difficulties presented, Christ taught exactly that - the need for supernatural help. The Ancient Near East, being an agrarian society, used terms like grain, seed, fruit, bread, etc. extensively, mostly to denote riches, and in the case of the Bible, teachings:
Luke 11:1 It happened that while Jesus was praying in a certain place, after He had finished, one of His disciples said to Him, “Lord, teach us to pray just as John also taught his disciples.” 2 And He said to them, “When you pray, say: 'Father, hallowed be Your name. Your kingdom come. 3 ‘Give us each day our daily bread. 4 ‘And forgive us our sins, For we ourselves also forgive everyone who is indebted to us. And lead us not into temptation.’” 5 Then He said to them, “Suppose one of you has a friend, and goes to him at midnight and says to him, ‘Friend, lend me three loaves; 6 for a friend of mine has come to me from a journey, and I have nothing to set before him’; 7 and from inside he answers and says, ‘Do not bother me; the door has already been shut and my children and I are in bed; I cannot get up and give you anything.’ 8 “I tell you, even though he will not get up and give him anything because he is his friend, yet because of his persistence he will get up and give him as much as he needs. 9 “So I say to you, ask, and it will be given to you; seek, and you will find; knock, and it will be opened to you. 10 “For everyone who asks, receives; and he who seeks, finds; and to him who knocks, it will be opened. 11 “Now suppose one of you fathers is asked by his son for a fish; he will not give him a snake instead of a fish, will he? 12 “Or if he is asked for an egg, he will not give him a scorpion, will he? 13 “If you then, being evil, know how to give good gifts to your children, how much more will your heavenly Father give the Holy Spirit to those who ask Him?”
Now to come to the specific question of how to comprehend what God requires from us.
Applying the method I mentioned, when I ask God for bread, enlightenment, this is how He answers:
God wants us to be blessings to the world, through learning how to be that blessing. When we are baptised in the name of Christ, we know that we will receive the Holy Spirit, necessary for learning the Way. When we receive the Holy Spirit, we will be taught that picking up a cross, every day, leads to being resurrected, every day. How does the Holy Spirit teach this? By displaying God's great work in saving.
Remember, when Israel committed to stop serving selfish interests, and start serving God through selflessness, God immediately created situations where dangerous conditions came up, and He then saved from those conditions. Conditions like food and water shortages. His miracles in the wilderness were performed to build up faith in Israel, just as they did when they were performed in Egypt.
This is exactly how God taught Abraham faith, when He was exposed to risk to his life, on account of Sarah. Although he lied, it didn't take him out of danger, and his rescue was clearly through God's help.
These situations teach two things, lessons Abraham learnt, but Israel did not. Abraham intuited that God required him to trust him to be saved from danger. Second, these rescues were connected to the promise that the world would be blessed through him and his descendants. They were situations in which the great works of God would be displayed, so that those witnessing them would be motivated to serve God, like Abraham served God. You see similar parallels in the great works God empowered Moses and Christ with.
Exodus 4:1Then Moses said, “What if they will not believe me or listen to what I say? For they may say, ‘The LORD has not appeared to you.’” 2The LORD said to him, “What is that in your hand?” And he said, “A staff.” 3Then He said, “Throw it on the ground.” So he threw it on the ground, and it became a serpent; and Moses fled from it. 4But the LORD said to Moses, “Stretch out your hand and grasp it by its tail”—so he stretched out his hand and caught it, and it became a staff in his hand— 5“that they may believe that the LORD, the God of their fathers, the God of Abraham, the God of Isaac, and the God of Jacob, has appeared to you.”
John 9:1As He passed by, He saw a man blind from birth. 2And His disciples asked Him, “Rabbi, who sinned, this man or his parents, that he would be born blind?” 3Jesus answered, “It was neither that this man sinned, nor his parents; but it was so that the works of God might be displayed in him.
So when God asked Abraham to sacrifice Isaac as an offering, Abraham thought that the event was just another opportunity to display God's great work, believing that God would raise his son back from the dead.
Hebrews 11:19He considered that God is able to raise people even from the dead, from which he also received him back as a type.
Baptism is induction into a course of comprehending what God requires of us, to become blessings to the world, a fulfilment of the promise to us, descendants of Abraham through faith in God. We are baptised into Christ, drink from the Rock, eat the same spiritual food, which will build up our faith in God, belief He will rescue. This was meant for the children, not for dogs, but faith makes us children of Abraham, like the syro-Phoenician woman. As for Israel, if the works done in her had been done in Sidon and Tyre, they would have turned to follow God, so her unbelief was great. After tasting the bread from heaven, if we do not believe in God's Way, and obey, when we hear God's voice to pick up our crosses, no other way is left to be saved.
We see that this conclusion was reached by being enlightened in a supernatural way, because seeing this motif buried in the forest of other motifs of Scripture would be impossible, if using any other method.
