What does the phrase 'the kingdom of God is not meat and drink' mean?

In Romans 14:17, Paul clarifies that the kingdom of God is not about physical sustenance but about righteousness, peace, and joy in the Holy Spirit. This statement serves to remind believers that while some may be concerned with dietary laws or religious practices, the essence of God's kingdom lies in our relationship with Christ and the transformative work of the Holy Spirit within us. It's not what we consume or abstain from that qualifies us as members of God's kingdom, but rather our faith in Christ and our resultant actions that demonstrate His love and righteousness through us.
