It's not OK to produce "Wood Hay and Stubble"

If anyone’s work is burned, he will suffer loss; but he himself will be saved, yet so as through fire. - 1 Cor 3:15

The sense of the Greek in here is not to say that it is "OK" not to be based one's work's on the firm foundation of Christ and produce "Wood, Hay and Stubble". But to one who built the foundation of one's faith upon worldly wisdom is threading at risk of going to Hell, equivalent to the English term, " to be saved at the skin of his teeth".

He continues to warn that if they persists on with their dependence on worldly wisdom, especially those who instigated others to do so, (Context from Chap 1 and 2), they will be at risk of losing their Salvation.

Do you not know that you are the temple of God and that the Spirit of God dwells in you? If anyone defiles the temple of God, God will destroy him. For the temple of God is holy, which temple you are. - 1 Cor 3:16-17
