"You know when I sit down and when I rise up; you discern my thoughts from afar. You search out my path and my lying down and are acquainted with all my ways. Even before a word is on my tongue, behold, O LORD, you know it altogether. You hem me in, behind and before, and lay your hand upon me. Such knowledge is too wonderful for me; it is high; I cannot attain it... Search me, O God, and know my heart! Try me and know my thoughts! And see if there be any grievous way in me, and lead me in the way everlasting!" - Psalms 139:2-6; 23-24 ESV
"And he entered Jerusalem and went into the temple. And when he had looked around at everything, as it was already late, he went out to Bethany with the twelve. On the following day, when they came from Bethany, he was hungry.
And seeing in the distance a fig tree in leaf, he went to see if he could find anything on it. When he came to it, he found nothing but leaves, for it was not the season for figs. And he said to it, 'May no one ever eat fruit from you again.' And his disciples heard it.
And they came to Jerusalem. And he entered the temple and began to drive out those who sold and those who bought in the temple, and he overturned the tables of the money-changers and the seats of those who sold pigeons. And he would not allow anyone to carry anything through the temple. And he was teaching them and saying to them, 'Is it not written, 'My house shall be called a house of prayer for all the nations'? But you have made it a den of robbers.' And the chief priests and the scribes heard it and were seeking a way to destroy him, for they feared him, because all the crowd was astonished at his teaching. And when evening came they went out of the city.
As they passed by in the morning, they saw the fig tree withered away to its roots. And Peter remembered and said to him, 'Rabbi, look! The fig tree that you cursed has withered.'
And Jesus answered them, 'Have faith in God. Truly, I say to you, whoever says to this mountain, 'Be taken up and thrown into the sea,' and does not doubt in his heart, but believes that what he says will come to pass, it will be done for him. Therefore I tell you, whatever you ask in prayer, believe that you have received it, and it will be yours. And whenever you stand praying, forgive, if you have anything against anyone, so that your Father also who is in heaven may forgive you your trespasses.' " - Mark 11:11-25 ESV
These are verses from a devotional I am reading. I see the parallel between the fig tree and thinking that is not nourishing. Grace and Gospel oriented thinking is the 'ancient pathway'... the way everlasting... and there is always something to eat there, in season or out of season, it multiplies and feeds.
That is the thought life that feeds us and is multiplied to feed others. Jesus describes it here...
"Jesus said, 'Have the people sit down.'
Now there was much grass in the place. So the men sat down, about five thousand in number. Jesus then took the loaves, and when he had given thanks, he distributed them to those who were seated. So also the fish, as much as they wanted. And when they had eaten their fill, he told his disciples, 'Gather up the leftover fragments, that nothing may be lost.'
So they gathered them up and filled twelve baskets with fragments from the five barley loaves left by those who had eaten...
When they found him on the other side of the sea, they said to him, 'Rabbi, when did you come here?'
Jesus answered them, 'Truly, truly, I say to you, you are seeking me, not because you saw signs, but because you ate your fill of the loaves. Do not work for the food that perishes, but for the food that endures to eternal life, which the Son of Man will give to you. For on him God the Father has set his seal.'
Then they said to him, 'What must we do, to be doing the works of God?'
Jesus answered them, 'This is the work of God, that you believe in him whom he has sent.'
So they said to him, 'Then what sign do you do, that we may see and believe you? What work do you perform? Our fathers ate the manna in the wilderness; as it is written, 'He gave them bread from heaven to eat.'
Jesus then said to them, 'Truly, truly, I say to you, it was not Moses who gave you the bread from heaven, but my Father gives you the true bread from heaven. For the bread of God is he who comes down from heaven and gives life to the world.'
They said to him, 'Sir, give us this bread always.'
Jesus said to them, 'I am the bread of life; whoever comes to me shall not hunger, and whoever believes in me shall never thirst.' - John 6:10-13, 25-35 ESV
Sit and eat. There is a tree that is cursed and bread that is blessed. Grace is the thinking that is blessed. Jesus is the bread of life. God's gift is eternal life to all who will take and eat.
