Death for the believer is to be with Christ
Philippians 1:21–23 (ASV)
21For to me to live is Christ, and to die is gain. 22But if to live in the flesh,—if this shall bring fruit from my work, then what I shall choose I know not. 23But I am in a strait betwixt the two, having the desire to depart and be with Christ; for it is very far better:
1 Thessalonians 4:13 (ASV)
13But we would not have you ignorant, brethren, concerning them that fall asleep; that ye sorrow not, even as the rest, who have no hope.
