Because Im too quiet... I can't make friends easily.. Must I displeasing God because of this attitude?
1 Peter 3:3-4 Let not yours be the [merely] external adorning with [elaborate] interweaving and knotting of the hair, the wearing of jewelry, or changes of clothes; But let it be the inward adorning and beauty of the hidden person of the heart, with the incorruptible and unfading charm of a gentle and peaceful spirit, which [is not anxious or wrought up, but] is very precious in the sight of God.
1 Corinthians 12:4 Now there are distinctive varieties and distributions of endowments (gifts, extraordinary powers distinguishing certain Christians, due to the power of divine grace operating in their souls by the Holy Spirit) and they vary, but the [Holy] Spirit remains the same.
You may not be an "easy" friend, but you may be a valuable friend. Those who have a quiet spirit can be used by God to minister to those who are agitated, anxious, or otherwise troubled by a hectic world. You can offer a haven of rest.
You do not need a "loud" personality to get noticed. You can physically stand near various people and groups. You will often be ignored, but since most people are unable to appreciate what is around them, it is actually a good thing that they ignore you. These sort of people are often unable to appreciate anything but a mirror.
You need someone as a friend who can appreciate you for who you are. This is getting more difficult to find in a world so oriented to selfishness. However, the wait is worth it. You can go to meetings, classes, or other group activities and see if the Lord will bring someone across your path who will notice and appreciate you for what and who you are.
