Non-believer or skeptic suggests that Christians are fearful of works of righteousness for salvation. Is this true?

If you were a Christian you would know that your eternity is secure in the covenant promise of the Father for anyone who believes and trusts and places their faith in Jesus Christ as our Lord for the mediation of sin (John 3:16-18) and once you’ve trusted in Jesus and established covenant relationship with the Father, that relationship is SEALED and Guaranteed by the Gift of the Holy Spirit (Ephesians 1:13-14) who takes-up residence within you and becomes your Tutor-your Guide-your Lord-your Wisdom (Galatians 5:16; John 14:16) and the Spirit leads you into good works of obedience that glorify the Father as the Spirit prepares you for service in the New Jerusalem.

The Christian is not fearful of good works but the Christian understands that any work done prior to having established covenant relationship with the Father is futile, nihilistic, as the Father is NOT glorified by your works of self-righteousness as those works are equated to a filthy, bloody, menstrual cloth in His nose (Isaiah 64:6; Ephesians 2:8-9). It is the works done SUBSEQUENT to covenant relationship by the Spirit through faith in Jesus that are accounted as works of righteousness to be judged at the BEMA Judgment of Christ as those works of righteousness validate and authenticate the faith that initially established covenant relationship.
