Think of your favorite flower...
Just as that flower needs sun, water, and proper soil to thrive, a Christian needs daily reading of the Word, nutrients from going to church each week and the foundation of Bible teaching.
The result, of course, is a lovely bloom. Similarly, one's heart will grow & transform into something beautiful when nourished.
The Bible says in Col. 2:6-7,
"Therefore as you have received Christ Jesus the Lord, so walk in Him, having been firmly rooted and now being built up in Him and established in your faith, just as you were instructed, and overflowing with gratitude."
This verse compares us to plants; ever noticed that before?
Our roots are firmly in Christ; now we're to be growing consistently in Him. Does this describe you?
