1 If ye then be risen with Christ, seek those things which are above, where Christ sitteth on the right hand of God.
2 Set your affection on things above, not on things on the earth.
3 For ye are dead, and your life is hid with Christ in God.
4 When Christ, who is our life, shall appear, then shall ye also appear with him in glory.
Colossians 3:1-4
34 And when he had called the people unto him with his disciples also, he said unto them, Whosoever will come after me, let him deny himself, and take up his cross, and follow me. 35 For whosoever will save his life shall lose it; but whosoever shall lose his life for my sake and the gospel’s, the same shall save it. 36 For what shall it profit a man, if he shall gain the whole world, and lose his own soul? 37 Or what shall a man give in exchange for his soul? 38 Whosoever therefore shall be ashamed of me and of my words in this adulterous and sinful generation; of him also shall the Son of man be ashamed, when he cometh in the glory of his Father with the holy angels.
Mark 8:34-38
