Beginning
Spiritually, "beginning" happens when we first start new growth -- new levels of awareness and willingness to receive goods and truths from the Lord, and use them. In the Word, "beginning" doesn't just mean the beginning of something in time. In the inner sense, it means the initial phase of a spiritual state.
1 Corinthians 15:27
27
For, "He put all things in subjection under his feet." But when he says, "all things are put in subjection," it is evident that he is excepted who subjected all things to him.
