A Contrite Heart
29 Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls.
30 For my yoke is easy, and my burden is light.
Meek and lowly in heart is a reflection on the OT word ‘contrite heart’. One writes:
” [of Ps 51:17] .. the sacrifices that are well pleasing to Him and most beloved by Him .. are thankfulness out of the fullness of a penitent and lowly heart.
” ..the inward part of man is said to be broken and crushed when his sinful nature is broken, his ungodly self is slain, his impenetrable hardness is softened, his haughty vainglorying brought low, – in fine, when he in himself become as nothing, and when God is everything to him. Of such a heart, panting after grace and favour, consist the sacrifices that are truly worth of God’s praise and well pleasing to Him. cf Isa 57:15 where such a spirit and such a heart are called God’s holy temple.” 
What is the image of Christ we are being conformed to?
Our activities can be limited in regards to those of Christ, due to the diversity of spiritual service gifts given to individuals.
Our personalities are the creation of God with which He chooses to work.
I would say that we are conformed to Christ’s attitudes, His mindset, that it the issue.
30 I can of mine own self do nothing: as I hear, I judge: and my judgment is just; because I seek not mine own will, but the will of the Father which hath sent me. (KJV)
29 And he that sent me is with me: the Father hath not left me alone; for I do always those things that please him. (KJV)
27 Now is my soul troubled; and what shall I say? Father, save me from this hour: but for this cause came I unto this hour. (KJV)
21 For even hereunto were ye called: because Christ also suffered for us, leaving us an example, that ye should follow his steps:
22 Who did no sin, neither was guile found in his mouth:
23 Who, when he was reviled, reviled not again; when he suffered, he threatened not; but committed himself to him that judgeth righteously:
6 Who, being in the form of God, thought it not robbery to be equal with God:
7 But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men:
8 And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross.
– Be willing to abide in all those things the Father provides – contentment
– In humility be totally subservient in attitude to the will of God – obedience.
– Be prepared to submit ourselves to the injustices incurred against us and entrust ourselves into the hands of the living God who will do right – (this refers, not as much with judicial matters as it does in response to personal offences) – meekness (1 Pet 4:12-19).
“But how many will submit to lie in the hand of their creator, leaving to Him full power to treat them as He will, making no resistance and caring not what the world will say.” 
HE WAS THUS PERFECTED BY HIS OBEDIENCE (HEB 5:6,9), AND OUR OBEDIENCE IS ALSO BASED ON SUBMITTING TO THAT WHICH GOD PROVIDES, AND COMMITTING ONESELF TO DO THOSE THINGS HE WOULD HAVE US DO – PUTTING AWAY ALL OUR OWN ASPIRATIONS FOR HIS GOOD WILL.
18 The LORD is nigh unto them that are of a broken heart; and saveth such as be of a contrite spirit. (KJV)
17 The sacrifices of God are a broken spirit: a broken and a contrite heart, O God, thou wilt not despise. (KJV)
15 For thus saith the high and lofty One that inhabiteth eternity, whose name is Holy; I dwell in the high and holy place, with him also that is of a contrite and humble spirit, to revive the spirit of the humble, and to revive the heart of the contrite ones. (KJV)
2 For all those things hath mine hand made, and all those things have been, saith the LORD: but to this man will I look, even to him that is poor and of a contrite spirit, and trembleth at my word. (KJV)
We often preach rules (which is often encouraged to gain favour with God or fallen man) not true righteousness received by faith.  See Phil 3:9.
HOW MUCH OF OUR CHRISTIANITY REFLECTS A CONTRITE HEART?
1 Keep thy foot when thou goest to the house of God, and be more ready to hear, than to give the sacrifice of fools: for they consider not that they do evil. (KJV)
FALSE PIETY? Matt 15:8f; Isa 58:2; Tit 1:16
IRREVERENT OF TRUTH AND PURITY? Josh 24:14; 1 Cor 5:8; Phil 1:9, 10; Ps 89:7; Heb 2:20
REWARDS WILL NOT BE BASED ON THE MEASUREMENT OF WHAT WAS ACCOMPLISHED BUT BASED ON INTEGRITY AND FAITHFULNESS. THIS IS OUR FAITH!
Based on this how shall we then live?
Tit 1:16; 2:6-8.. acceptance based on conformity to our social peer pressure? Isa 29:13; Appeasing God for of punishment or loss? or thanksgiving – Eph 2:4-10
How shall we then work?
2 Cor 1:12.. self righteous by comparison with others? Gaining merit by our obedience. or faithfulness 1 Cor 4:2; Lk 17:10.

 “… the teaching of Christ is absloute and fundamental contrariety to that of the Rabbis (Pharisee’s). According to Jesus Christ, when we have done all, we are to feel that we are but unprofitable servants. According to the Rabbis, as St. Paul puts it, ‘righteousness comes by the Law;’ and, when it is lost, the Law alone can restore life; while, according to Christrian teaching, it only bringeth death.”The Life and Times of Jesus the Messiah; by Alfred Edershiem; Eerdmans; Vol 1; pg 509
