He wanted to

Ephesians 1

3 All praise to God, the Father of our Lord Jesus Christ, 

who has blessed us with every spiritual blessing in the heavenly realms 

because we are united with Christ. 

4 Even before he made the world, 

God loved us 

and chose us in Christ 

to be holy 

and without fault in his eyes. 

5 God decided in advance to adopt us into his own family 

by bringing us to himself through Jesus Christ. 

This is what he wanted to do, 

and it gave him great pleasure.
