you really got your stuff wrong —
Romans 8:35-39 - death cannot separate us from Christ.
35 Who shall separate us from the love of Christ? shall tribulation, or distress, or persecution, or famine, or nakedness, or peril, or sword?
— we are in Christ - and death has no sting. We ask our fellow Christians who are with Christ to pray for us.
Romans 12:5 - we are one body in Christ, individual parts of one another
Romans 12:10 - love one another with mutual affection
1 Corinthians 12:12-27 – If one part is hurt (suffers), all the parts share its pain. And if one part is honored, all the parts share its joy
Galatians 6:2 - bear one another’s burdens
Galatians 6:10 - let us do good to all, especially to those in the family of faith
Ephesians 1:22-23 - he is the head of the Church, which is His Body
Ephesians 4:4 - one body, one spirit, called to one hope
Ephesians 5:21-32 - Christ is the Head of the Church, savior
Colossians 1:18, 24 - he is the head of the body, the Church Colossians 3:15 - you were called in one body
We are one Body in Christ - and HE who has conquered death brings us to life everlasting in His bosom where we pray for others still on this mortal coil.
Lots of verses Cronos, but not a single one advocates praying to a departed saint, nor is there a record from before 100 AD that an Apostle ever did this...
