When we understand our Father and His law, we know that the basic law is to love God, the second is to love man. Every law God gives can be measured by this.
Matthew 22: 35 to 40:
35 And one of them, an expert in the law, asked a question to test Him: 36 “Teacher, which command in the law is the greatest?”
37 He said to him, “Love the Lord your God with all your heart, with all your soul, and with all your mind. )38 This is the greatest and most important command.39 The second is like it: Love your neighbor as yourself.40 All the Law and the Prophets depend on these two commands.”
From this we know that the law that “the two shall become one” through sex stems from God’s love for us. A society where this is listened to is a happy, stable society with a family that can be depended on, where love flourishes. When it is broken there is much unhappiness that follows. In the case of rape, sin has happened and unhappiness follows. God wants goodness and happiness for us. God follows the law of love, and if you are hurt God comes to our defense.
If there is guilty feelings, those feelings and that guilt can be taken to Christ who died for our sins and you can be wiped as clean as snow, like the old hymn says. It needs to be taken just once, then accept the forgiveness forever with faith.
As for God completely forgiving us when we take our sins to Him with repentance. Scripture often tells us so. Mark 3:28 is a favorite of mine.
28 I assure you: People will be forgiven for all sins and whatever blasphemies( they may blaspheme.
When Jesus was scolded for what they considered working on he Sabbath because he plucked wheat when they were hungry even though their rules said he shouldn’t Jesus explained that the Sabbath was made for man. So is “the two shall become one” principle. God does not want us to suffer because of a law, that goes against the law of love. In the same way, God has compassion for anyone who is raped.
