How do we know that God dwells in us?

The assurance that God dwells in believers comes from the internal change brought about by the Holy Spirit. In 1 Corinthians 3:16-17, Paul affirms that the Spirit of God resides within all who are united to Christ. This indwelling manifests through a changed heart and a desire for holiness, revealing the transformative power of grace in a believer's life. As God walks in His people and proclaims Himself as their God, this relationship becomes evident through a lifestyle marked by obedience and separation from worldly entanglements.

Moreover, the witness of the Holy Spirit confirms our position as children of God. Romans 8:16 states, 'The Spirit himself bears witness with our spirit that we are children of God.' This internal confirmation is often accompanied by a yearning for godliness and a desire to engage in good works. Therefore, the believer’s life will reflect a commitment to holiness, leading to assurance that God indeed dwells within them, guiding and sustaining them in their walk of faith.
