Your idea of sanctification is from another age. It is like someone telling us to have a horse and buggy in the age you should be driving an automobile. You are still following the instructions on how to care for a horse and have thrown your spiritual car keys away. You're religion has misled you and has you living in a wrong age.
2 Thessalonians 2:13
But we ought always to thank God for you, brothers and sisters loved by the Lord,
because God chose you as first fruits to be saved through the sanctifying work
of the Spirit and through belief in the truth.
1 Peter 1:1-2
Peter, an apostle of Jesus Christ,To Gods elect, exiles scattered throughout the
provinces of Pontus, Galatia, Cappadocia, Asia and Bithynia, who have been chosen
according to the foreknowledge of God the Father, through the sanctifying work
of the Spirit, to be obedient to Jesus Christ and sprinkled with his blood: Grace and
peace be yours in abundance.
Acts 26:17-18
I will rescue you from your own people and from the Gentiles. I am sending you
to them to open their eyes and turn them from darkness to light, and from the power
of Satan to God, so that they may receive forgiveness of sins and a place among those
who are sanctified by faith in me.
1 Corinthians 1:1-3
Paul, called to be an apostle of Christ Jesus by the will of God, and our brother
Sosthenes, To the church of God in Corinth,to those sanctified in Christ Jesus
and called to be his holy people, together with all those everywhere who call on
the name of our Lord Jesus Christtheir Lord and ours: Grace and peace to you
from God our Father and the Lord Jesus Christ.
Our sanctification came through the the blood of Christ. No longer by trying to follow the mandates of the Law. For, if we walk in the Spirit, our nature will be changed, and we will find ourself abiding in this life which is according to the Law.. But, not according to the rituals found in the Law, which were only used of God as training tools to teach and prepare the Jews for the atonement that would come by means of the death, burial, and resurrection of Jesus Christ.
You need to come to know and understand that you have been sanctified by the Blood of Christ, and set apart (sanctified) by means of the Spirit in regeneration. You are now being duped by those who are exploiting your nice nature that has a willingness to be religiously obedient, wanting to be seen as good outwardly by following rules that have been set forth, so that if you do them, to give you a sense of being approved that you seek from God.
