John 2:18 The Jews therefore answered him, "What sign do you show to us, seeing that you do these things?" John 2:19 Jesus answered them, "Destroy this temple, and in three days I will raise it up."
By comparing scripture with scripture, it appears that Jesus was not here speaking of his being raised from the dead, but of his raising his body, which he did when he made his appearance in the closed/locked room. (Luke 24:36-39; John 20:19,20) Nevertheless, before Jesus could raise his body, his God and Father had to first raise Jesus' soul out of the oblivious condition of sheol/hades, in the spirit, not in the flesh. -- Psalm 16:10; Ecclesiastes 9:10; Acts 2:24,32,32,26; 3:15; 4:10; 10:40; 13:30,33,37; 17:31; Romans 4:24; 8:11; 10:9; 1 Corinthians 6:14; 15:15; Galatians 1:1; Colossians 2:11,12; 1 Thessalonians 1:9,10; Hebrews 5:7; 1 Peter 1:21; 3:18.
