Colossians 3:1-3

1 If then you were raised together with Christ, seek the things that are above, where Christ is, seated on the right hand of God.  2 Set your mind on the things that are above, not on the things that are on the earth.  3 For you died, and your life is hidden with Christ in God. 

Matthew 16:24-25

24 Then Jesus said to his disciples, “If anyone desires to come after me, let him deny himself, and take up his cross, and follow me.  25 For whoever desires to save his life will lose it, and whoever will lose his life for my sake will find it.
