Salvation is so personal: we are His sheep; we can hear His voice; and—the way we know we are His comes from following His voice.
Think of a shepherd who speaks, and of sheep that turn their heads, listen, and then start walking towards him. That is true Christianity!
Following Christ’s voice in His Word and thus following Him: that is assurance, that is salvation; and that is all reduced to FOLLOWING Him!
Now as we turn on to Titus 2:7, we come to the second desire God has for every man. If you are a young man, God is asking: “Are you FOLLOWING Me so that your LIFE a PATTERN for others to follow?”
