Teaching the Trinity with gifts (1Cor 12:4-6)

Some try describing Trinity with Egg, some water, some sun

Paul uses gifts, ministry, and effects

Now there are varieties of gifts, but the same Spirit. And there are varieties of ministries, and the same Lord. There are varieties of effects, but the same God who works all things in all persons.
1 CORINTHIANS 12:4‭-‬6 NASB

The purpose of gifts is ministry for others. Effectively seeing God working in all persons.
