If people belittle you then it’s because they have a very bad self image, corrupted and distorted by pride. Good looks without humility and a loving gentle kind heart is like a pig 🐖 with a golden ring in it’s nose. The golden ring cannot disguise the true nature of the pig.
By putting you down, they seek to make themselves look better, God sees their heart.
A person with a healthy GODLY self image seeks to make people feel good about themselves, because they understand that God sees us as fearfully and wonderfully made by Him, even if we don’t fit into the mold of our critics.
Only be concerned about God’s opinion about you beloved and see all of your faults, your weaknesses, your shortcomings and imperfections as an opportunity for Him to show himself strong on your behalf and always recall 1 Thessalonians 5:23 And the very God of peace sanctify you wholly; and I pray God your whole spirit and soul and body be preserved blameless unto the coming of our Lord Jesus Christ.
Philippines 1: 6 Being confident of this very thing, that God who has begun a good work in you will perform and complete it until the day of Jesus Christ:
YOU KNOW WHO YOU ARE, WHEN YOU’VE BEEN RAISED BY YOUR FATHER.
