23 Nevertheless, I am continually with you;
you hold my right hand.
24 You guide me with your counsel,and afterward you will receive me to glory.
25 Whom have I in heaven but you?
And there is nothing on earth that I desire besides you.
26 My flesh and my heart may fail,
but God is the strength  of my heart and my portion forever
7 Do not be deceived: God is not mocked, for whatever one sows, that will he also reap. 8 For the one who sows to his own flesh will from the flesh reap corruption, but the one who sows to the Spirit will from the Spirit reap eternal life. 9 And let us not grow weary of doing good, for in due season we will reap, if we do not give up. 10 So then, as we have opportunity, let us do good to everyone, and especially to those who are of the household of faith.
24 Then Jesus told his disciples, “If anyone would come after me, let him deny himself and take up his cross and follow me. 25 For whoever would save his life will lose it, but whoever loses his life for my sake will find it. 26 For what will it profit a man if he gains the whole world and forfeits his soul? Or what shall a man give in return for his soul? 27 For the Son of Man is going to come with his angels in the glory of his Father, and then he will repay each person according to what he has done. 28 Truly, I say to you, there are some standing here who will not taste death until they see the Son of Man coming in his kingdom.”
The above reminds me of Bonhoeffer's book on discipleship---some good quotes:
Quotes from Bonhoeffer:
“Cheap graced is the deadly enemy of our Church. We are fighting to-day for costly grace.”
“Cheap grace…amounts to a denial of the living Word of God, in fact, a denial of the Incarnation of the Word of God.”
“Cheap grace means the justification of sin without the justification of the sinner.”
“Let the Christian beware of rebelling against the free and boundless grace of God and desecrating it.”
“Cheap grace is grace without discipleship, grace without the cross, grace without Jesus Christ, living and incarnate.”
“Costly grace is the treasure hidden in the field; for the sake of it a man will gladly go and sell all that he has. It is the pearl of great price to buy which the merchant will sell all his goods. It is the kingly rule of Christ, for whose sake a man will pluck out the eye which causes him to stumble; it is the call of Jesus Christ at which the disciple leaves his nets and follows him.
“Such grace is costly because it calls us to follow, and it is grace because it calls us to follow Jesus Christ. It is costly because it costs a man his life, and it is grace because it gives a man the only true life. It is costly because it condemns sin, and grace because it justifies the sinner. Above all, it is costly because it cost God the life of his Son: ‘ye were bought at a price……Above all, it is grace because God did not reckon his Son too dear a price to pay for our life, but delivered him up for us. Costly grace is the Incarnation of God.”
“Luther laid hold upon grace. Just as the whole world of monasticism was crashing about him in ruins, he saw God in Christ stretching forth his hand to save. He grasped that hand in faith, believing that ‘after all, nothing we can do is of any avail, however good a life we live.’ The grace which gave itself to him was a costly grace, and it shattered his whole existence.”
“Happy are they who know that discipleship simply means the life which springs from grace, and that grace simply means discipleship. Happy are they who have become Christians in this sense of the word. For them the word of grace has proved a fountain of mercy.”
