"Some 'Christian' denominations teach that you can pray to your loved ones or to saints who have died and that they will hear you. Hmm do they really? You may argue that you do not pray to them but talk to them only, so what wrong with that?
You may argue that while they await for the resurrection nothing stopping them to help their close one still alive and you may argue that the dead saint intervene on our behalf, after all they are closer to God then us. By saying this, you are showing your doubt on the present of Jesus in your life. He is never too busy, and too tire to listen to you and to help you. Jesus continually invites us to rest in Him. It pleases Him that you trust Him and that you wait for Him.
Matthew 28:18 And Jesus came and spoke to them, saying, "All authority has been given to Me in heaven and on earth." As a Christians, are we not called to trust in Him for all our needs? We are invited to be in fellowship with Him and the Father. That is the reason Jesus die for us, to close the gap (sin) that was separating us.
