Its not possible for the natural man to please God Rom 8:8, yet Faith is pleasing to God, however sinners in the flesh, the natural man cannot produce Faith. God must first work by giving a sinner a new birth otherwise the natural man would not have Faith and could not have Faith, nor do anything that could please God, do you understand ?
Don't forget that the Holy Spirit of God sanctifies the sinner. Sometimes sanctification is instantaneous and sometimes it takes longer( up to a lifetime). Meanwhile, the person might still be in the flesh until the Holy Spirit changes him completely. Even Paul stuggled with his flesh. We are not to judge the person but his actions.
