In verse one, Jesus warns his disciples of false theologies, salvations, and leaders. They are the ones who bypass the gate and climb in some other way. These men, women and ideas are thieves and robbers.
Then Jesus goes on (verse 3) to describe how his disciples will know him. “He calls his own sheep by name and leads them out [of the sheep pen].” But, he goes on to say that the sheep follow him, “because they know his voice”. This is very important, because it reminds us that we need to passionately pursue Christ’s voice. We need to learn to listen and recognize his voice.
In verse five, Jesus says that his sheep “will never follow a stranger”. This is because they will “not recognize a stranger’s voice”. Rather than being confident that you will never follow a stranger, we should focus on following Jesus. For if we can recognize his voice, we will recognize the fallacy in the stranger’s voice. Therefore we should test every teaching and “hold on to what is good, [and] reject every kind of evil” (1 Thes. 5:21-22).
In verse seven, Jesus essentially states that He is the only way to heaven. There can be no multiple ways to get to heaven because everyone must “[enter] through me” and he who does this “will be saved”. This is a very important point and one that we all should strive to focus on, for “the gate is narrow and the way is hard that leads to life, and those who find it are few” (Matt. 7:14). Though this path is difficult, Jesus promises us that we “may have life, and have it to the full” (Jn. 10:10) if we follow him and enter through The Gate.
