You can't pick the laws you wish to obey

Read Galatians 2

For through the law I died to the law 

so that I might live for God. 

I have been crucified with Christ

 and I no longer live, 

but Christ lives in me. 

The life I live in the body, 

I live by the faith in the son of God, 

who loved me and gave himself for me.

“I do not set aside the grace of God for 

if righteousness could be gained though the law

Christ die for nothing.

                                                                                     Galatians 2:19-21
Paul makes it clear we can’t choose the law when it suits us and lay aside grace. Either we live under the law which cannot save us or we live under grace.
Many in the church today mix the Old Testament teachings with the New Testament. They conveniently pick the laws they choose to follow and forget about the rest.
The law is their to show us right from wrong. This in itself is not a problem. The problem arrises when those within the church choose to pick which laws they wish to observe.
There are many out there who say capital punishment is supported by the bible. Which it is. But the bible also forbids the eating of shell fish and pork.
Do those who are out there justifying capital punishment by using the bible also refrain from eating shell fish and pork?
You can’t have it both ways. This is what Paul was saying. We now live under grace.
I firmly believe that Christ came at a crossroads in time. God knew a new era in the world was beginning. That’s why he sent Christ when he did.
God knew the gentile world would have a hard time with some of the laws. That in parts of the world especially in the times of the early church it may be impossible to even obey the laws, especially the food laws at times. That’s why he made it easy for us to obtain salvation.
The Council in Jerusalem recognized that there was a new era coming. In Acts 15 it made a simple statement to the gentile believers.

“It seemed good to the Holy Spirit  and to us 

not to burden you with anything 

beyond the following requirements; 

you are to abstain from food sacrificed to idols, 

from blood, 

and from the meat of straggled animals

 and from sexual immorality 

you will do well to avoid these things. 

                                                                                                     Acts 15:28,29
Something to think about.
The message of Christianity is one of love and forgiveness. Not rules and regulations that cannot save anyone. It is about freedom not do’s and don’t.
God want’s us to live for him and not sin. We should never sin deliberately. Paul make it clear in Romans salvation through faith is not a licence to sin.
Still when we sin, and we all do, it is important to know we can turn to God and as John states, “If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.”
                                 1 John 1:9  
That is the message of Christianity. God’s loving us so much that he sent His Son to die for the forgiveness for our sin.
