Don't ever allow yourself to swallow somebody else's words when they don't even trust that you will understand them in the first place.
This is because no relationship in life can blossom without mutual trust.
So you are not obliged to succumb to their demands and/or desires, their hopes and dreams. It's different from the loving sacrifice of and for loved ones. While love is service, it is not the magnitude of your actions that matter, rather the attitude of your heart in the doing.
Not everyone who says they love you knows love. Though these people keep telling you to trust that they have the best of intentions, that you shouldn't have low opinions about them because of their nagging (which you shouldn't), not all of them have true faith, much less have faith in you. Therefore, it is impossible to fulfill their need to either a) get you under their control, or b) stop themselves from worrying.
The harsh truth is that sometimes, these people include mom and dad. We need Jesus as much as you do.
But know this: Even before you came into this world, we already believe in you. Because of our faith, Jesus has entrusted you with us.
So keep doing what God has called you to do, even if we don't always understand you, because He is the most reliable place to put your confidence in.
{ The fear of human opinion disables; trusting in God protects you from that. Proverbs 29:25 MSG }
{ Now faith is the substance of things hoped for, the evidence of things not seen. For by it the elders obtained a good testimony. By faith we understand that the worlds were framed by the word of God, so that the things which are seen were not made of things which are visible. Hebrews 11:1-3 NKJV }
{ But without faith it is impossible to please Him, for he who comes to God must believe that He is, and that He is a rewarder of those who diligently seek Him. Hebrews 11:6 NKJV }
{ I may speak in different languages of people or even angels. But if I do not have love, I am only a noisy bell or a crashing cymbal. I may have the gift of prophecy. I may understand all the secret things of God and have all knowledge, and I may have faith so great I can move mountains. But even with all these things, if I do not have love, then I am nothing. I may give away everything I have, and I may even give my body as an offering to be burned. But I gain nothing if I do not have love. 1 Corinthians 13:1-3 NCV }
{ while we do not look at the things which are seen, but at the things which are not seen. For the things which are seen are temporary, but the things which are not seen are eternal. 2 Corinthians 4:18 NKJV }
