For who among men knows the thoughts of a man except the spirit of the man which is in him? Even so the thoughts of God no one knows except the Spirit of God.
1 Corinthians 2:11
As Peter wrote, we have become partakers of God’s divine nature through His precious and magnificent promises (2 Peter 1:4). Now, we are His children, and as His children, we have the right to become ‘like God’, in the degree that He makes available.
Paul makes it clear that we are growing. We do not begin in perfect faith, but we grow in faith, and mature, both individually and corporately, until we reach maturity. This implies change, and this implies growth. It is enough to be like Him.
[U]ntil we all attain to the unity of the faith, and of the knowledge of the Son of God, to a mature man, to the measure of the stature which belongs to the fullness of Christ.
Ephesians 4:13
