We must always have our faith according to Scripture.
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.
For my yoke is easy, and my burden is light. (Matthew 11)
Therefore, Jesus' way is easy and light, especially when compared to the way of the world and the religions of man.
If we see it as hard, it is because of us, not because of Jesus' salvation and justification.
Good understanding giveth favour: but the way of transgressors is hard. (Prov 13)
What is hard is seeking to please God while sinning, it's not possible.
And so, we must first acknowledge sinning has no place in Christ Jesus, then we must learn why, where, and how sinning begins.
It's not by a sin nature, because there is no such thing created by Christ, neither in heaven nor in man, nor is it the mortal body's fault, but rather it comes from the same place it came from within Lucifer, who is the first one to sin against God: Lust for sin comes from within the heart, not from the flesh, but rather from the spirit of man desiring to sin with the flesh.
And so, the solution is of course simple: Purify the heart first, that the life in the flesh may be clean.
Let the wicked forsake his way, and the unrighteous man his thoughts: and let him return unto the LORD, and he will have mercy upon him; and to our God, for he will abundantly pardon. (Isaiah 55)
Thou blind Pharisee, cleanse first that which is within the cup and platter, that the outside of them may be clean also. (Matthew 23)
For though we walk in the flesh, we do not war after the flesh: (For the weapons of our warfare are not carnal, but mighty through God to the pulling down of strong holds;)
Casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ. (2 Cor 10)
The battle therefore is not with the flesh, but within the heart, to choose being pure in heart by bringing all thoughts into subjection to Christ, or to choose taking thought for unrighteousness within the heart, which will in due time be sinned with the flesh.
The fight against sin for righteousness is spiritual, not carnal, and so the fight is won or lost within the heart and the mind of man.
If we are double hearted in Romans 7, we will be in the hard way of sinning against Jesus with knowledge, but if we purify the heart to become single-eyed upon Jesus only, then we are delivered into Romans 8 and cannot sin with the flesh, since there is no lust from the spirit to do so.
There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit. For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death. (Rom 8)
Whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God. (1 John 3)
The only way of Jesus is the easy and simple way of having a pure heart and clean conscience of not sinning against Him, first within the heart, and so also with the body.
The ongoing work, fight, and race is within, not without.
Trying to resist sinning with the flesh by the will of the flesh is failure at the start.
We resist the devil within the heart and mind by the Spirit, because that is where he attacks, and is where he is defeated.
Above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked. (Eph 6)
He flees not just from us, but from us walking hand in hand with Jesus, How can the devil tempt any man to lust, who loves supping with Jesus in the kingdom of God within?
It's simple: purify the mind and guard the heart from taking thought for sinning, and so keep the body from doing so.
All it takes is the power and Spirit of Christ Jesus within us. to do so daily without fail.
Yep, that all it takes: the power of the Almighty God and Christ Jesus within.
But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name: Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God. (John 1)
People who are still taken into sin at the will of the devil, are not being overtaken by a sin nature of the flesh, there being no such thing, but are just not exercising the power of Christ to resist taking any such thought to do so.
The thoughts certainly come to mind, as the fowls of the air swooping down to rob Abraham of his sacrifice pieces, but Jesus commands us
today to chase them all away and take no thought for them.
Take therefore no thought for the morrow: for the morrow shall take thought for the things of itself. Sufficient unto the day is the evil thereof. (Matthew 6)
The true secret to all this is simply caring only for the inward battle at hand, not for any imagined battle tomorrow, which may never even come.
When any Christian begins to fight the good fight within by the faith and power of Jesus Christ, he or she will then know where the fight is won, and knows it is as simple and easy as quenching the fiery darts at the door: DOA.
No man sins with the flesh, who did not want to from the heart. The mortal body is just mortal not sinful.
