Why do you see walking, resting and breathing to be sinful? Jesus knew no sin, but was made the sin sacrifice for everyone.
We walk in the Spirit
Gal 5:16 This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh.
Gal 5:17 For the flesh lusteth against the Spirit, and the Spirit against the flesh: and these are contrary the one to the other: so that ye cannot do the things that ye would.
Eph 5:1 Be ye therefore followers of God, as dear children;
Eph 5:2 And walk in love, as Christ also hath loved us, and hath given himself for us an offering and a sacrifice to God for a sweetsmelling savour.
Rest in Christ
Mat 11:28 Come unto me, all ye that labour and are heavy laden, and I will give you rest.
Mat 11:29 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.
Mat 11:30 For my yoke is easy, and my burden is light.
Breathing
Gen 2:7 And the LORD God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul.
John 3:16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
John 3:17 For God sent not his Son into the world to condemn the world; but that the world through him might be saved.
John 3:18 He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.
John 3:19 And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil.
John 3:20 For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved.
John 3:21 But he that doeth truth cometh to the light, that his deeds may be made manifest, that they are wrought in God.
2Cor 5:17 Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.
2Cor 5:18 And all things are of God, who hath reconciled us to himself by Jesus Christ, and hath given to us the ministry of reconciliation;
2Cor 5:19 To wit, that God was in Christ, reconciling the world unto himself, not imputing their trespasses unto them; and hath committed unto us the word of reconciliation.
2Cor 5:20 Now then we are ambassadors for Christ, as though God did beseech you by us: we pray you in Christ's stead, be ye reconciled to God.
2Cor 5:21 For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him.
