“Sin is anything that separates you from God”
“Nothing a person does can separate him from God.”
While your statement is very true from God’s perspective, it is not true from the human perspective. Our sin blocks us from experiencing God. This is the reason that Jesus forgave people in order to heal people’s souls and cure illness that was caused by sin.
Therein lays the problem with Christian churches today. Nothing in the New Testament scriptures supports such nonsense. Jesus dealt with the sin problem over 2,000 years ago.
Then how was I able to experience God?
