Hebrews 8:7

"For if that first covenant had been faultless, there would have been no occasion sought for a second".

"Hebrews 8:7 says; “For if there had been nothing wrong with that first covenant” (talking about the law covenant) “no place would have been sought for another”. There was something wrong with that first covenant. That’s why another covenant had to come. The grace covenant that had already been established in eternity! (v8); “For God found fault with the people”. The law covenant is a faultfinding covenant. It is based on you and your performance and so God scrutinises your performance through the law. There is no way you can please God because we are always falling short and always messing up. God always must find fault with us through the law. That covenant is a terrible covenant and that is why Jesus said; “Come to Me those that are heavy-laden, weighed down and crushed”. Why? Because they were living under a faultfinding covenant".
