Sunflowers, in order to grow, chase the sun, which is the “author and perfecter of their faith…” (Heb. 12:2), that being the faith that they will grow. They look to the sun because “God is light, and in Him there is no darkness at all.” (1 John 1:5), and “The Son (sun) is the radiance of God’s glory and the exact representation of his being…” (Heb. 1:3), and in the Son, who is Christ, “all the fullness of deity lives in bodily form.” (Col. 2:9)
Because of this, sunflowers “walk in the light as God Himself is in the light” so that they may have fellowship with one another, and so that the blood of Jesus Christ will cleanse them from all sin.” (1 John 1:7)
They have been “foreknown by God,” and have been “predestined to be conformed to the image of God’s Son…” (Romans 8:29)
And so, in blooming, they are “reflecting the Lord’s glory,” and “are being transformed into the same image from one degree of glory to another…” (2 Cor. 3:18)
Through faith, Christ dwells in their heart, so that, because they “have been rooted and grounded in love,” they “may be able to comprehend with all the saints what is the breadth and length and height and depth, and thus to know the love of Christ that surpasses knowledge,” so that they “may be filled up to all the fullness of God.” (Eph. 3:17-19)
Through His divine power, and because of his promises, they can become “partakers of the divine nature.” (2 Peter 1:3-4)
In other words, they bear the image and the glory of the sun.
“And just as we have borne the image of the man of dust, let us also bear the image of the man of heaven.” (1 Corinthians 15:49)
