As you read Matt. 5:24 the mention of the word brother would show the context of the whole teaching of the chap. in v.27-28 Jesus is going to take things a step further than what was said in the past by saying now a better principle to abide in. If you look upon a woman to lust after her you are just as if you commited the act. v.29-30 the two verses are repeating the statement cast into hell. 2 things I perceive here. 1. That if while a single person is going through the help find a mate services they are putting themselves in a dangerous position to lust, also they will get to see a picture of her. He'll probably check out her endowments as he looks. I am certain that the scripture is speaking to already saved Christians. Is it not? also saying that a brother could find themselves in hell?? Please consider praying that God will help you find the right mate, especially one who is a strong Christian to help you in your service for the Lord.
