Forerunners move out from the crowd they've been running with, to a place ahead of the crowd, where they are an example for others. As a result, it is not uncommon for forerunners to feel isolated, alone.
You need to know that that’s not isolation: that’s forerunning: it’s part of the job description of a forerunner – running ahead of the crowd, not with it – and that solitude is part of God’s provision for you. (Remember how Jesus sought it out? eg. Mark 6:45-46)
Others among the crowd see your example and move forward to join the forerunner or to even move beyond you. So the forerunner will have an empty spot, a vacuum, behind you, where others used to be, where others used to be. The more effective a forerunner is at bringing others forward, the greater the vacuum. Anyone trying to pull away from that vacuum will feel the vacuum pulling back.
Forerunners, that’s one of the things you’re fighting: you need to stay out of that vacuum; you may feel forces pulling you back. Resist the influences trying to pull you back to where you used to be. You need to keep pressing forward, keep reaching for the high calling in Christ Jesus. That’s who you are; that’s how you’re made.
There are others who need to move forward to fill that space behind you, who need to draft behind you, who will be encouraged to keep the pace you set.
Therefore, since we are surrounded by such a great cloud of witnesses, let us throw off everything that hinders and the sin that so easily entangles. And let us run with perseverance the race marked out for us…. (Hebrews 12:1)
