also All who come to Christ are saved from being slaves to sin...Colossians 1:13 talks about how we were brought out from the darkness and into the kingdom of Christ. Ezekiel 36:26 talks about receiving a new heart and a new spirit put within us = the mind of Christ and the Holy Spirit... The issue is that after receiving all of this some people still choose operate from the old mind,old ways, not being slaves anymore, but still bound by old sinful habits because they have not yet learned how to function as a new creation in Christ and also not renewing their mind Romans 12:2.. the apostles gave instruction on how to live after being saved, but some people choose to neglect everything beyond the book of Matthew... People have options and choices to make, some don't know what they have, some choose to neglect it,some just flat out understand and walk in it completely, and some don't yet know but are learning and growing.. The best thing to do for anyone is to give them the truth of God and let them walk wherever they choose, cant force anyone into the kingdom or judge anyone for making dumb choices.. God judges a person by their heart, just have faith that his will be done always. and pray for those who fall.. sometimes they have to hit rock bottom to reach out to God so they can come back again.
