If you were the only one on the face of the earth, Jesus would still have come to die for you. He died for you personally. Not many have thought about it. They think Jesus died for the world; and to them, the world means nature and the things in it. He died for you! Appropriate and meditate on this deeply. It happened over two thousand years ago; but let it be refreshed in your consciousness today; and it'll produce results in you.
You were bought with a price. You're valuable to God. You're not a nobody! It doesn't matter that you seem to be "down" in life right now; it doesn't matter what the society has made you! It just doesn't matter that you seem to have been relegated to the background. The best description of you isn't what people call you or describe you to be; heaven's description of you is what counts.
You're the righteousness of God in Christ Jesus (2 Corinthians 5:21). You've been washed, sanctified, and justified in the name of the Lord Jesus, and by the Spirit of God (1 Corinthians 6:11). You're heaven's best: "Of his own will begat he us with the word of truth, that we should be a kind of firstfruits of his creatures" (James 1:18). You're peculiar, royal, excellent and full of glory; you're SOMEBODY SPECIAL! That's why Jesus died for you. He loves you.
Read our opening scripture again and see how valuable you are to God. I love the first word of 1 John 3:2, it says, "BELOVED, now are we the sons of God..." (1 John 3:2). You're beloved of God. Stop being bothered that nobody loves you. Love others, because God loves you.
Perhaps you didn't realize how beloved and special you are to God; now that you know, accept it, and endorse it. It'll give you a new self-value.
