(Duh.) But more specifically…
Isaiah 61:1-3 says:
The Spirit of the Sovereign Lord is on me, because the Lord has anointed me to proclaim good news to the poor. He has sent me to bind up the brokenhearted, to proclaim freedom for the captives and release from darkness for the prisoners, to proclaim the year of the Lord’s favor and the day of vengeance of our God, to comfort all who mourn, and provide for those who grieve in Zion— to bestow on them a crown of beauty instead of ashes, the oil of joy instead of mourning, and a garment of praise instead of a spirit of despair. They will be called oaks of righteousness, a planting of the Lord for the display of his splendor.
Elah is Hebrew for oak. Roots are where oaks derive their source of life. Deep roots mean the tree is not easily moved from where it draws its life. Roots of Elah is about:
Seeking God’s glory in all things, all the time
Walking in obedience to His will with an eternal perspective
Pointing back to His Glory, always
Encouragement to build the Kingdom of God in our everyday lives
