How do we know that God is with us in spirit?

In Colossians 2:5, Paul states, 'For though I be absent in the flesh, yet am I with you in the spirit.' This verse illustrates the profound truth that God's Spirit connects believers regardless of physical distance. The nature of spiritual connection is rooted in the indwelling presence of the Holy Spirit, who unites us with Christ and one another. This doctrine affirms that we can experience fellowship with fellow believers and God Himself, even when we are apart. This unity is essential for encouraging one another to grow in faith.
