 This is something that you absolutely need to hear especially when you go through times where you doubt your walk whether you are an actual believer. But Jesus says this about us as believers. He calls us sheep and he says that his sheep follow him. We hear his voice and we follow him. He says this in John chapter 10 and he also says that he leads out his own meaning that we are his. Something else he also describes about us as sheep. He says that when a stranger's voice is heard we don't listen to it. We turn and run away. Why? Because we're his sheep. We follow him. Do we follow him in a straight line? No. There are times where we kind of zigzag and so forth but ultimately our lives are indicative of us following him and because we're his own he will always come and get us even if we stray off course. And the real comfort is in verse 27. He says my sheep hear my voice. I know them and they follow me. And then in 28 he says that I give them eternal life. They shall never perish. Neither shall anyone snatch them out of my hands. So we see that we'll keep following and no one can snatch us out of his hand and the assurance is that we will never perish.
