“even as he chose us in him before the foundation of the world, that we should be holy and blameless before him. In love”
Ephesians 1:4 [ESV]
We must read verse three as we look at this verse above. “Praise be to the Lord and father of our Lord Jesus Christ, who has blessed us in the heavenly realms with every spiritual blessing in Christ.“
- We receive every spiritual blessing IN Christ
- The Father chose us IN Christ
- We are holy and blameless IN Christ
It’s all about Christ and being IN Him.  Our journey into blessing, began in eternity past. There is nothing we did to generate His decision to choose us. No entitlement. The link to verse three is that He blessed us even as He elected us. This makes our God a relational God. He picked us out for Himself. 
This whole idea is that this is what makes us (the church) a specifically called group, we are called the “in Christ“ group. My position in Christ leaves me blameless and holy because of the work of Christ. Love is the sphere that comes from God’s act of election. It is a moving toward another with his or her best interest at heart; not an emotional response.
Application:
When I accepted the Lord Jesus Christ as my Savior, I received all of the spiritual blessings I could ever have because I was born into Christ. It is only through a deep study of God‘s word and a relationship with God through prayer, that I can unlock all of the things that are already inside of me that God has for me.  the key is to realize that the Holy Spirit is the activator. When someone colors their hair they could put just the color-dye in their hair but until they mix in the activator/developer, the color just sits there; it doesn’t penetrate.  The Holy Spirit acts through a pure heart, a heart justified through salvation in the Lord Jesus Christ.  My growth happens through meditation on God‘s word and dedicating my life and service to Him.  The other way that I have spiritual growth is through persevering through trial and leaning into God’s strength in the midst of it.
