John 3:11-12 Truly, truly, I say to you, we speak of what we know, and bear witness to what we have seen; but you do not receive our testimony. If I have told you earthly things and you do not believe, how can you believe if I tell you heavenly things?

The Trinity is a mystery. Amen.

That's really all there is, that's all you need to know. Everything else only explains what this means. You see, a mystery, by definition is something that you cannot by reason understand by reason. And reason is very important to us, often we are not happy unless we understand - tell me why?

But faith is full of mystery, and we are saved by faith, and not by reason. Who can explain how God created the world out of nothing? Who can explain why God worked 6 days on creation and rested on the 7th. Who knows why God so loved the world?

When we really look at ourselves, when our conscience, the law written in our hearts shows us our sins - we can have all sorts of reasons (or excuses) - but we see our sin, and we see that we deserve the wrath of God - we see that all our good works are but filthy rags - and yet we hear that God so loved the world, that he gave his only begotten son, that whosoever believeth on him should not perish, but have everlasting life. Why it's a mystery! Itís a mystery why God should love poor miserable sinners so much. Itís a mystery that Jesus should suffer and die for our sins. Itís a mystery, that from the cross, Jesus request was - Father forgive them.

Itís a mystery that children can hear and believe and be saved. Itís a mystery, that the more we grow, the more we question, and the more we try to understand, the harder it is for us to believe, There's a reason for that - for the older we get the more we see, that all men are sinners - and sinners are not trustworthy, and it is not reasonable to believe and trust, and we learn all about disappointment.

Itís a mystery that we can be born again, but such a wonderful mystery - can you imagine what would happen to us if we could not be born again - think - what happens to things that are broken these days? And if we were not just thrown away, imagine eternal life - being mended and patched - forever scared by every sin and transgression? But we ARE born again, not just once at baptism, when our sins are washed away - but we are born again every time we remember or baptism, and drown our old sinful nature [that repentance] - and rise to the new life that is ours in Christ. The blood of Jesus not only washes away our sins, and makes us a new creation but the Spirit, working through the word, creates faith that can believe the promises of God.

Why is this important? Because of reason - we make a god of reason, we've simply got to understand everything - and so God makes us children again, so we can accept things by faith, so we can believe and be saved - and God gives us this faith in Christ through the Spirit.

Which brings us back to the beginning - The Trinity is a mystery. Not a mystery in the usual sense, of a "who dun it" - because this has been revealed. We know of the work of God the Father. We know of the work of God the Son. We know of the work of God the Holy Spirit. We know that there are three persons. We know that there is one God. We know it, not because we understand how - but by faith we believe what God in his Word has revealed.

We believe God loves us, not because we understand why - but simply, like children, because God says he loves us - that's faith! And it is by faith we believe what God has revealed, that there is one only God, and in the one God there are three persons - its so simple!

God said it, I believe it, that settles it!
