Funny thing about opening a door is that you don't know how hard you're going to have to push on it until you just start to open it. Sometimes it requires little effort and sometimes it takes all the strength you've got to get it open and go through. And the time factor - it might take a bit of time to push open a very heavy door . . .
So it is with pressing in to God or going to the next place He's called you. It's like a door before you. You've got to take that first step of pushing into Him. It may not require a lot of strength, not a lot from your mind, will or emotions because they are ready or because of His grace. Yet at other times, it will require every bit of your strength; your mind, will and emotions. But every door He has for you is worth it!
But it is good for me to draw near to God: I have put my trust in the Lord GOD, that I may declare all thy works. Psalm 73:28
