First, of course, a child needs to be born



You have maybe heard the saying that having a baby changes everything. When someone stops going one's own selfish way, and trusts in Jesus, there is rejoicing in Heaven. And we know how when a baby is first born, there is rejoicing and heavenly delight and anticipation for the family and friends.
So, first it is about stopping the way we have lived selfishly and often have been in joy-dead and love-dead stuff, often only desperate to try to ease boredom and loneliness and nasty angry reacting and arguing; or we have tried to run ahead of these miserable and degrading things, by keeping ourselves busy with pleasure seeking and adrenaline rush stuff.
But we see how a little child can be pleased with picking up a pebble. Enough is enough, to keep a little child alive with interest.
And when the ones who so love and care for the unborn know it is about that time, all of a sudden we see the crib show up, the diapers, the foods, and other things . . . ready for the baby to be welcome home. Like this, with God, He is the One who prepares for someone to trust in Jesus and become forgiven and to become adopted as a newborn of God.
And then, as we grow as God's children, we keep discovering how He already has people and things ready for what He knows He will have us ready to to. It is like how you know when your young child is ready to start learning to ride a bike. A bike appears in your timing

The right people are there for encouraging and guiding the child.
It is like this, with God. However, plenty of Christians will understandably take issue with me saying all will be ready for doing God's will. But we are the ones who do not first make sure we get the real correction which we need > Hebrews 12:4-11 < so we are ready to obey how our Heavenly Father will take care of us ! ! Once we mature more in character of love and peace and joy and abiding in humble submission to God, we more readily keep with God and His timing for all He is committed to doing with us.
And, like this, a child needs correction to learn how to relate in love and sharing with the child's parents. And then the child can learn how to relate in love so the child can later do well in marriage and helping to bring up younger children.
