Commentaries:
Robertson's Word Pictures (NT)
For if we believe (ei gar pisteuomen). Condition of first class, assuming the death and resurrection of Jesus to be true.
In Jesus (dia tou Ihsou). Literally, through or by means of Jesus. It is amphibolous in position and can be taken either with touv koimhqentav (that are fallen asleep in or through Jesus) like oi koimhqentev en Xristw in I Corinthians 15:18 and probably correct or with acei (through Jesus with God).
With him (sun autw). Together with Jesus. Jesus is the connecting link (dia) for those that sleep (koimhqentav first aorist passive, but with middle sense) and their resurrection.
