Serving The Lord is different to serving others. When we serve others with no thought for doing the Lord's Will, we may finish up in servitude to others' selfish demands. Answers to prayer come often while serving The Lord in His Way.
ALWAYS be confident in your decisions. Live life for you. If someone doesn't like it i guess they don't have your best interest in mind. only you can make the decisions that will change your life into what you want it to be.
