1 John 3:6
"No one who lives in him keep on sinning. No one who continues to sin has either seen him or known him."NIV
"Whosoever abideth in him sinneth not: whosoever sinneth hath not seen him neither known him."KJV
When we have truly given our lives to Jesus Christ, our hearts cannot tolerate any ongoing sin in our lives because the Holy Spirit continually convicts us until we forsake the sin we have held onto. If we see anyone who claims to be a Christian and they have a lifestyle that includes things that are sinful, they have not met the Saviour nor given their lives to Him.
Heavenly Father, we ask that Your Holy Spirit search our hearts for any lifestyle or habitual sin we may be harboring and tuning out the Holy Spirit. We pray for those who do so. Give us hearts that are pure and work to stay away from sin. In Jesus' name we pray, Amen.
