1 Peter 1:13-16

Therefore gird up the loins of your mind, be sober, and rest your hope fully upon the grace that is to be brought to you at the revelation of Jesus Christ;
as obedient children, not conforming yourselves to the former lusts, as in your ignorance;
but as He who called you is holy, you also be holy in all your conduct,
because it is written, “Be holy, for I am holy”.

Colossians 3:1-4

If then you were raised with Christ, seek those things which are above, where Christ is, sitting at the right hand of God.
Set your mind on things above, not on things on the earth.
For you died, and your life is hidden with Christ in God.
When Christ who is our life appears, then you also will appear with Him in glory.
