Should I pursue?

I was asking the Lord yesterday about a matter I had once got an answer from Him. It was so clear then, but doubt starts to sink in my heart again whether He had really wanted me to take up the matter. I wanted very much to move on from it, because sometimes it seems easier that way. To bring the matter up again really goes against what is natural.
I would think that since God said in His Word to do a New thing for us, why not just let go of that and trust the 'New' thing in my life to manifest. But turning away from facing it and letting go is altogether different. We find it easier sometimes to run away from the thing that He wants us to conquer. I was sharing with one of my close fren yesterday from kl about this matter. And she say that it's not about what I think will happen or what I do next with it but what the Lord is telling me. It's about fighting for what is rightfully mine and to conquer it. It might be a blessing behind it.
And to my amazement, as I flip open to one of Michelle McKinney Hammond's book today, that very passage I read really got me thinking again. It sounded like what she told me the last time we spoke and yesterday. It was the story of David and Goliath that she shared that made me want to pursue it initially.
"...Everything that happens to u always comes back, full circle, to God's purpose being fulfilled. Yes, there are giants in the land. But this reality should not make us settle for the leeks, onions, and hopeless relationship in Egypt. Decide that you are willing to fight for what is rightfully yours. Make up your mind that you won't let go until God blesses you(sound like Jacob:)). You must be willing to look your soul's giants straight in the eye and then slay them. As he helped David kill Goliath with a single blow to the head, God will help you. But He seeks your cooperation. Look into the mirror of your soul and ask God to expose everything in you that He wants to fix in preparation for that glorious possession into the promised land."
As I think of it now, it's silly if David would have said I'll let go of the 'giants' in my life and trust God for a new thing. We have choices to some giants in our lives. David could have chosen to run away from it or go ahead with it. He may then just remain as a Shepherd boy if he had not step out in faith. But because He went ahead to face Goliath, he became a King. 
After all that was said, I pray that the Lord will strengthen my heart to meet the 'giants' in my life. Just got reminded of what Pastor Lian preached recently. All David had to do before God could work in his life was to 'show up'. How true.
