You can have a personal and intimate relationship with God who is not silent, but who speaks to man in this day and age. However that relationship doesn't come by accepting Him, but by surrendering to Him.
A personal relationship with God is obtained and enhanced by faithful and earnest prayer. The Bible instructs us to pray to the Father (Matthew 6:6-13). This is the channel by which we can communicate with God and receive His grace.
We often think that God doesn't care if we pray to Jesus or the Father, but if God has given us a command, shouldn't we, because we love Him, want to obey? How can we expect an intimate relationship with our Creator if we ignore His commands?
