I understand that preaching is part of God's process.
It may be like how you discover a person you so love and you desire to have children with each other.
First > the fact you love each other is what destines a thing or two
So, then there are other things which become destined . . . maybe like you will build a house . . . or a hut . . . together, so you have a place to stay and share and care for children.
And, along with that comes various other process items which are included for bringing to pass how your love has destined that you will have children.
All of that which is in the process is also destined.
And I personally see how Isaiah 55:11 says God's word is destined to do all which God Himself means. And so, His word is His manual, guaranteed to accomplish what He pleases. And this can be good to rest in, knowing how humans can make it look as though no one can figure out what God's word means for us to believe and do. We can trust Him to do all He means, in sharing with us
And I trust that Isaiah 55:11 guarantees that God's word is doing and shall continue to do all He means. So, this is destined. His word is destined, then; and so, God Himself is destined, maybe we can consider.
But . . . so . . . about preaching > if it is an action of God, then deeper than the words, preaching can be spreading the almighty power of grace to have God's effect. It is like to how the LORD spoke what would be created, then He produced the result which He intended by His words of creation. Every word, then, is God's spoken word with God Himself to produce His meaning >
"for it is God who works in you both to will and to do for His good pleasure." (Philippians 2:13)
So, do not stop at preaching, then. There is all which His word means for us who have trusted in Christ . . . for how we live and love as family, in personal sharing with God and in submission to Him in His peace (Colossians 3:15), while being changed to be and love like Jesus > Ephesians 5:2 > Romans 8:29.
And our example can be spreading the effect of grace to those around us. For example, we can feed on how wives can help a disobedient man >
"without a word" > 1 Peter 3:1-4.
God's redeeming almighty creative enlivening continues after He saves someone.
