“...indeed our fellowship is with the Father, and with His Son Jesus Christ.” 1 John 1:3
One marvelous reason for which God has adopted us (Eph. 1:5), indeed part of the very “calling” to become God’s children, is to fellowship (1 Cor. 1:9) with the great God of Creation!
Jesus prayed (John 17) that we, His chosen disciples, might have the same kind of relationship with the Heavenly Father that Jesus Himself had throughout eternity. Our minds may not totally grasp that wonder down here – except as we try to understand something of the key of walking “in the light” (1 John 1:7).
The nature of light in our universe gives us clues:
Light is unchangeable; one cannot make light dark.
Light exposes everything (reveals and brings clarity).
Light is the sustainer of all life as we know it.
The nature of darkness is also very instructive:
Darkness is driven away by the smallest spark.
Darkness covers everything (hides and obscures).
Darkness will kill all life as we know it.
“But the path of the righteous is like the light of dawn...The way of the wicked is like darkness...” (Prov. 4:18-19). The promise of fellowship with God is that He “will lead the blind by a way they do not know, In paths they do not know”...and that He...“will make darkness into light before them and rugged places into plains” (Isaiah 42:16).
Therefore, “since we are of the day, let us be sober, having put on the breastplate of faith and love, and as a helmet, the hope of salvation” (1 Thess. 5:8). Since we were “formerly darkness” but have been delivered from “domain of darkness” (Col. 1:13), we should no longer “participate in the unfruitful deeds of darkness, but instead even expose them” (Eph. 5:11).
