How do we know the Holy Spirit is necessary for Christians?

The necessity of the Holy Spirit for Christians is highlighted in scripture, particularly in 2 Corinthians 4:6, where Paul declares that God shines light in our hearts. This indicates that without the Holy Spirit, individuals remain in darkness and cannot comprehend spiritual truths or live rightly before God. By nature, we are spiritually dead and cannot produce light by ourselves. The gift of the Holy Spirit, given through Christ’s sacrifice, provides the enlightenment and conviction needed for obedience and holiness. The Holy Spirit continually glorifies Christ and ensures that the believers’ light shines brightly in a dark world.
