In Ephesians 3 Paul uses some important imagery in communicating spiritual reality.
17 that Christ may dwell in your hearts through faith; that you, being rooted and grounded in love, 18 may be able to comprehend with all the saints what is the width and length and depth and height – 19 to know the love of Christ which passes knowledge; that you may be filled with all the fullness of God. Ephesians 3:17-19 (NKJV)
Contained in these verses we have the idea of being rooted and grounded followed by a shift to width, length, depth and height. Paul is covering all of the dimensions but telling us that knowing the reality of the dimensions is dependent on being rooted and grounded, not just in anything, but in love, the love of Christ.
Even a well rooted tree can come down if planted in the wrong place, what is around it is important. If you look at the pictures below there are two significant trees. One is already in the creek and over time will be swept away, the other is still rooted but on a crumbling bank that will give way over time and it is only a matter of time before that tree will also end up in the creek and be swept away. There are numerous trees in both pictures that are safely away from the eroding power of the creek.
It is a question of where are we planted and whether we are we rooted and grounded in a safe place. Jesus love is the only secure place to be rooted and grounded yet we cannot plant ourselves there. We can pursue Jesus love but we need to be strengthened by the Holy Spirit in our inner being to be securely planted.
16 that He would grant you, according to the riches of His glory, to be strengthened with might through His Spirit in the inner man, Ephesians 3:16 (NKJV)
If we want to know the width, length, depth and height of Jesus love then let us ask Him to strengthen our inner being so that we can both be rooted in, and bear the reality of, the width, length, depth and height of His love – knowing His love in every dimension of our life!
