As the old chinese saying goes, 'As we live to a ripe old age, so we will learn to a ripe old age'. The hardwares need to be changed over time as we grow in maturity. The hard disk needs to be upgraded to have larger space to accomodate the things that we have learnt. The softwares need to be up to date with the newest technology available to be relevant to the world and aligned with God's new move and plan. We must always rely on our only Authorized dealer, Jesus and not violate the warranty. Finally, our power comes from the ultimate source of all, God our heavenly Father.
The mental transformation in this computer analogy would be the downloading or updating of new software. It is a process that will take time and it will involve the changing of ingrained perceptions, thoughts and habits. It involves the passing of the old and installation of the new. This is the process of the renewing of our mind.
'And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God.' Romans 12:2
