Imagine, if you will, a trail. A trail on the side of a mountain. The dirt trail is cluttered with roots and foliage that scratch your ankles and calves as you make your way down the slippery slope. It's dusk and to make matters worse it rained last night, making the trail muddy and slippery. The trail starts to get steeper and the night starts to grow around you. It's hard to see and you start slipping in the mud. You try and slow down, but your legs just keep going, your feet just keep sliding. Part of you is enjoying the thrill, the free-for-all sensation you have, but part of you knows you need to stop before you fall of the trail.
That's what it's like with sin. You taste what the world has to offer. Just a little bit, when you think no one is looking. Pretty soon you are gliding along, skimming on the wrong trail. You know you need to stop, not sure how you got here. That when you quote Psalms 94.
18 When I said, “My foot is slipping,”
your unfailing love, LORD, supported me.
You ask God to help you. You ask him for forgiveness and he gives it freely, as well as his never failing love. He will support you. He will bring you back to the trail of his will. We have all been there. We have all sinned and gotten off the beaten path, onto one that we know is of our own doing, not God's. But he is there, waiting for you to let him know that your "foot is slipping". So stop skimming and start depending on his grace to get you through.
