Why can’t non-Christians talk to Jesus?
Because they’re not connected to God the Father…because they haven’t believed on the One who God the Father sent. And the only way to connect to God the Father is to believe in (to trust in and rely upon) the One He sent, His only begotten (unique one-of-a-kind) Son. And to believe in Jesus is to believe that His voluntary, sacrificial, vicarious, atoning death on the cross is the only provision for my sin problem - in other words, Jesus’ death on the cross is the only way for me to be forgiven of my sin and to be put in right-standing with God the Father. So, since non-Christians haven’t done this, they’re not connected to God the Father; therefore God the Father does not hear their prayers. But if they’ll humble themselves and cry out for mercy and ask for forgiveness, God WILL hear that prayer.
