Hopefully making theology simpler to understand! (2 Corinthians 1:12)

Whatever you do, work heartily, as for the Lord and not for men, knowing that from the Lord you will receive the inheritance as your reward. You are serving the Lord Christ.
Colossians 3:23‭-‬24, ESV

Everything we do in life – our work, our relationships, our helping others, and sharing the gospel – we realize we are directly serving Jesus. He is the God of our whole lives, not merely parts.
