We do not have the power on our own to stop doing bad things. We cannot. We human nature is ruled by the flesh. That flesh always wars against the spirit. It makes it difficult for us to do what good we have the desire to do. We are not able on our own to stop doing what is bad.
The human mind is carnal. It is dominated by the flesh. The flesh desires things that are contrary to the purpose of God. The flesh longs after worldly and carnal affections. It is very impossible that any man born of a woman will be able to please God on his own.
We need the help of God to be able to please God. We need the grace of God to overcome the carnal pleasures warring against us everyday. We need the empowerment of God to overcome all the evil tendencies surrounding us. We need the Holy Spirit to help us.
It is by the Holy Spirit of God so that our minds can be regenerated to conform to the purpose and will of God. We cannot be true disciples of Jesus Christ who truly obey His commandments and doctrines if we do not have the Holy Spirit. We must receive the Holy Spirit so that we can overcome the evil and do the right.
