Ephesians 1:3

Blessed be the God and Father of our Lord Jesus Christ, who hath blessed us with all spiritual blessings in heavenly places in Christ.

God through Jesus made available to us all the spiritual blessings. When we renew our minds and grow in knowledge of those promises our eyes open to the truth of the bible.  We must then step out and practice our faith like a child on small things.  Bit by bit and step by step we use the word and develop until we just glance at a mountain and it trembles.
