Committing murder, theft or sexual sin is a choice. Being tempted to murder, steal, commit sexual sin or any other temptation is not sin. We all have a sinful nature, which is why we need to be born again of the Holy Spirit, baptised in water and baptised in the Holy Spirit, We all need grace, mercy, love and His power within us to grow to be more like Him.
Our beliefs need to be formed by the Word of God and the Holy Spirit - not formed from our own minds and experiences. Jesus said 'I am the way and the truth and the life'
God bless
