A living stone are being built into a spiritual house

1 Peter 2:1-8
Get rid of all 1)malice and all 2)deceit, 3)hypocrisy, 4)envy and 5)slander of every kind.
Like new born babies, craves pure spiritual milk, so that by it you may grow up in your salvation.
Come to him, like living stone, are being built into a spiritual house to be a holy priesthood, offering spiritual sacrifices acceptable to God through Jesus Christ.
Don't get stuck at the baby stage, Peter says to his readers. Grow up in faith! Remember who you are: God's own people, chosen to make known the wonderful things he has done; living stones being built into a spiritual Temple that rests on the foundation stone of Christ himself.
Living stone: A favourite New Testament metaphor for Christ. The quotations are from Isaiah 28:16; Psalm 118:22; Isaiah 8:14-15
Why?
Malice, deceit, hypocrisy, envy, slander all are shown on many peoples for their own benefit. But we are Christian, should get rid of these all.
New born babies craves pure mile, so as we should crave pure spiritual milk, then we may grow up in our salvation. Don't stuck at baby stage, can't do witness for the Lord.
I am living stone, being built into a spiritual house. I am the witness of the Lord. I am a holy priesthood. It have to be holy. All of these are based on foundation of Jesus Christ.
How?
What do I earnest to the pure spiritual milk- God's words? Yes. But I know I have some fault in my life, I need to get rid of all sins to be a living stone in Christ.
