There are a lot of things to worry about. Money, work, politics, your house, your car, you reputation... and if you have kids this worry just seems to go up ten fold! Plus added to all of earths worries comes the inborn anxiety for some of us. We don't even need a reason to worry, we just do any way!
And if you have reached a certain age, you probably by now have some tools to help you with fear, worry, and anxiety.
- Relationships with friends and family.
- Pharmaceutical drugs.
- Varies herbs and plants (legal and otherwise!)
- TV and various forms of entertainment.
- And many have various addictions who's root can go back to some fear, worry anxiety etc...
And some of these things really can help - for a time at least in some cases. But real help comes from God - your Creator, your Savior, and your Comforter.
Jesus says here in this verse as He's talking about when he leaves His disciples, that they should not worry. Because He was leaving behind His peace. This is the peace that Jesus had here on earth. For Jesus knew His mission, His purpose. And you, as his follower, can have this peace too.
