Ruth was looking for a redeemer, someone who could give her back all the things that sin and death had taken from her.
She had found herself at the feet of her redeemer and asked for redemption.
She was about to receive her redemption.
Salvation is as simple as our asking for it (John 6:37; Rom 10:13, James 4:2).
Jesus Christ has done everything necessary to save the soul of lost sinner.
All that sinner has to do is to humble himself before the LORD God and ask for salvation.
Remember Ruth, she was redeemed because she asked for it.
