You said: "If the sign gifts are for now.. they would be operating in decency and order."
Well then according to this logic, no one should believe in Christ because, clearly, many Christians are 'out of order and sorts'.
The Holy Spirit has not stopped from pouring out those Precious Gifts - and HE does not need anyone's approval either.
This is why we have the Word of God - to know the Truth via the Spirit of Truth and Gifts of the Spirit.
And He Himself gave some
to be apostles, some prophets, some evangelists, and some pastors and teachers,
12for the equipping of the saints for the work of ministry, for the
[e]edifying of the body of Christ,
13till we all come to the unity of the faith and of the knowledge of the Son of God, to a perfect man, to the measure of the stature of the fullness of Christ;
14that we should no longer be children, tossed to and fro and carried about with every wind of doctrine, by the trickery of men, in the cunning craftiness of deceitful plotting,
15but, speaking the truth in love, may grow up in all things into Him who is the head—Christ—
16from whom the whole body, joined and knit together by what every joint supplies, according to the effective working by which every part does its share, causes growth of the body for the edifying of itself in love.
