How does one walk in obedience to the Father’s will as a Christian? 

Christian response,  

You don’t require a man, a pastor, a church, a theologian, to teach you what is expected of you as a Christian but your Teacher, as you fervently study the Scriptures, is the indwelling Holy Spirit (1 John 2:27) and all you must do is seek Him and listen to Him and trust in Him as He will faithfully guide you in the Father’s will through the conscience apart from the futility of law-keeping and subservience to letters that do not engender conformity to the Father’s will (2 Corinthians 3:6). 

The Holy Spirit is the LIGHT of Jesus; it is the Holy Spirit who introduces Himself in Genesis 1:2 as the logistical overseer of creation; it is the Spirit who implanted Jesus in the womb of Mary (Luke 1:35); it is the Spirit who raised Jesus from the dead (Romans 8:11-13); it is the Spirit who empowered Jesus during His ministry for 3.5-years upon this Earth and it is the Spirit who will empower you to live a Godly and obedient life within the Realm of Time if you surrender completely to Him and walk in His Light (Zechariah 4:6; Galatians 5:16); finally, it is the Holy Spirit who is the Guarantor and the Seal of Covenant Relationship with the Father for everyone who believes that Jesus is Messiah who died for them (Ephesians 1:13-14; John 3). 

The commandments of Jesus provided during His ministry are taught by the Spirit as well (John 14:26) as the words of Jesus are the Father’s will for your life; therefore, walk in the Holy Spirit and you will not conform to the lust of the World (Galatians 5:16).
