Is God younger than you?

We had a guest speaker in our church (an ozzie), and he said something which seems on the outside fascinating.
When the devil caused sin to enter our world the period of aging began and now we take it as normal that we have our allotted time of three score and ten (70 years) or there abouts (on average) to live out our lives.
We know from the bible that people pre-Noah's time lived far longer, i.e. Methuselah lived 969 years.
It was not God's original intention that we grow old so quickly. This is a cause of sin in our lives.
Jesus says let the children come to him.
God wants us to have a simple faith in him. To believe him and trust in him without us complicating things and making provisos or ifs and buts, but just to trust him, like a child simply trusts its parent without question.
My child trusts me even though he has often no clue what I am doing. I say to him, come we are going out in the car, and he tags along because a) he enjoys going out in the car, b) because he enjoys being with me, whereever I go and whatever I do.
This is how God wants us to be.
Could it be that we age to become older than God? That God is an eternal child in simplicity and without complication? He sets down the rules and he never changes. There are no provisos. No ifs and buts with God. He wants us to simply love him and trust him. His rules are there to keep us close to him, like we tell a child not to wander off or stick their grubby fingers in the electrical sockets. Those rules keep them safe and God's rules are designed to keep us safe in him.
That's all he wants folks........
