An object In Act is a perfect (complete) object, matching its form.
An object In Act can either be a motionless, dead, finished object, or it can be an object that is only matching its form when it is “operating”, which is what a perfect, complete, finished, living being does - operation is its Actuality, which growing to the point where it would finally be able to operate is TIME.
But when it is operating, it is not in time (other than accidental temporal features of the operation do participate Time).
God, the LORD, also known in English as ‘I AM’, is eternal Act in operation, as his Son stated about him always working.
