How do you view guys? Do you see them as a Brother (in Christ) or a Lover?
It's an easy thing to slip into doing the second one, as seeing each guy around our age, a potential 'lover'.
I want us to be honest with ourselves, even when it's painful. Let us ask ourselves this question, and give ourselves a true answer. You don't have to share it with anyone else, besides God, of course, but it's important to know where your motives come from.
When we're walking through a store, and we see a guy that we think is not so bad looking, do we see him as someone we could 'have a crush on' or a brother in Christ?
I, just like the next gal, don't always catch myself to think of every guy as a brother in Christ. And that's where it needs to start. We need to first see every man as a brother in Christ, and if God desires something more to become of it, than it will, but we are then comforted with the knowledge that he was first our brother in Christ, and we held no impure notions about him.
By our own will we cannot just switch our thinking. It's not going to happen just like *that*. It is going to have to come from the Lord. Our strength comes from the Lord, and this is also considered a strength we need, in my opinion.
Today we treat our emotions, and feelings toward the opposite sex as if they are nothing, really. They don't matter that much, do they? But they do. This is a area we need to be daily praying about and for. We need to hand over the key to our King, and let Him guard our hearts and emotions how He desires to. It isn't up to us alone. But through Jesus Christ our King. He will take care of us, and steer our thoughts to Him, if we let Him. And it will be something that we have to work on too, because Satan wants our minds pulled away from the Lord. But "You will keep him in perfect peace whose mind is stayed on You, because he trusts in You." which is found in Isaiah :)
Next time you look at a guy, ask God to let you see him how the Lord sees him. Let's surrender all to God, and count it gain.
