"Cherry-picking" is a term used to lie about Christians. It is meant to confuse people and decieve them into thinking that Christians pick and chose what to believe.
The fact is there is a reason why some parts of the Bible are not applicable to Christians.
The New Covenatnt was prophesied in the Old Covenant times. Jesus brought in the New Covenant. The church has never been under the old one.
Mat 26:28 For this is my blood of the new testament, which is shed for many for the remission of sins.
Jer 31:31-34 Behold, the days come, saith the LORD, that I will make a new covenant ... this shall be the covenant that I will make ...I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people.... And they shall teach no more every man his neighbour, and every man his brother, saying, Know the LORD: for they shall all know me, from the least of them unto the greatest of them, saith the LORD: for I will forgive their iniquity, and I will remember their sin no more.
Under the New Covenant we recieve the Spirit as the prophet Joel also prophesied would happen in th New Covenant. (Joel 2:27-32)
Act 2:38 Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.
Act 2:39 For the promise is unto you, and to your children, and to all that are afar off, even as many as the Lord our God shall call.
The ceremonial law was not carried over into the New Covenant. Ceremonial law was a shadow pointing towards the coming of Christ. Christ, the reality of the shadow, has come.
Col 2:16 Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath days:
Col 2:17 Which are a shadow of things to come; but the body is of Christ.
Col 2:20 Wherefore if ye be dead with Christ from the rudiments of the world, why, as though living in the world, are ye subject to ordinances,
Col 2:21 (Touch not; taste not; handle not;
Mat 5:17 Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.
1) The ceremonial law pointed to Christ and is fulfilled in him.
2) Jesus perfectly obeyed the Law.
3) Jesus paid our penalty for breaking the Law.
The Law could not give us the strength to live right but the Spirit that we receive in the New Covenant can.
Rom 8:1 There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit.
Rom 8:2 For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death.
Rom 8:3 For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh:
Rom 8:4 That the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit.
The moral law as you see is still in effect. The requirements of the moral law are righteous.
