Unhappy in church? There's a reason for that.

The law is still being taught in most churches today, and as a result:

2 Corinthians 3:7 - 18
The Glory of the New Covenant 
7 Now if the ministry that brought death, which was engraved in letters on stone, came with glory, so that the Israelites could not look steadily at the face of Moses because of its glory, fading though it was, 8 will not the ministry of the Spirit be even more glorious? 9 If the ministry that condemns men is glorious, how much more glorious is the ministry that brings righteousness! 10 For what was glorious has no glory now in comparison with the surpassing glory. 11 And if what was fading away came with glory, how much greater is the glory of that which lasts! 
12 Therefore, since we have such a hope, we are very bold. 13 We are not like Moses, who would put a veil over his face to keep the Israelites from gazing at it while the radiance was fading away. 14 But their minds were made dull, for to this day the same veil remains when the old covenant is read. It has not been removed, because only in Christ is it taken away. 15 Even to this day when Moses is read, a veil covers their hearts. 16 But whenever anyone turns to the Lord, the veil is taken away. 17 Now the Lord is the Spirit, and where the Spirit of the Lord is, there is freedom. 18 And we, who with unveiled faces all reflect the Lord’s glory, are being transformed into his likeness with ever-increasing glory, which comes from the Lord, who is the Spirit.
