Christ died to set us free from sin & from a long list of laws & regulations.
Trying to be saved by keeping the Law & being saved by grace are two different approaches.
We are saved by faith, not works, but love for others & for God is the response of those whom God has been forgiven.
It only takes one person to infect all the others by persuasion.
Persecution proved that the apostle Paul was preaching the true Gospel.
The "flesh" is not a reference to the body, but to the sinful nature that attempts to use our bodies to lead us into sin.
At the same time, you must beware of confusing your feelings with the Spirit's leading. Being led by the Holy Spirit involves the desire to hear, the readiness to obey God's Word, & the sensitivity to discern between your feelings & his promptings.
The Holy Spirit is infinitely stronger, but we are weak. Our only way to freedom from our natural evil desires is through the empowering of the Holy Spirit.
