Be ye therefore perfect even as your Father which is in Heaven is perfect. Matt. 5:48
One of satans wiles is to bewitch the children of light to think they need not be free from sin to enter Heavens gates. Altho overcoming sin is not all there is to the Christian life it certainly is very important.
Most Pentecostal groups now espouse Evangelical teachings, one will never in this life overcome sin. This is very deadly thinking.
Christ Jesus will not marry a bride with sin in her life.
25Husbands, love your wives, even as Christ also loved the church, and gave himself for it; 26That he might sanctify and cleanse it with the washing of water by the word,
27That he might present it to himself a glorious church, not having spot, or wrinkle, or any such thing; but that it should be holy and without blemish. Ephesians 5:25-27
