Being secure can mean a lot of things in different contexts. 

For example, you can be secure in your finances, health, marriage, or job -- even secure in your own abilities.

That being said, you could argue that, in fact, nothing is TRULY secure because life is REALLY good at throwing the most aggressive curve balls.

One fine day you could be walking along enjoying your privilege and then you could get fired, or someone could betray you, or you could find out that you are sick -- and suddenly everything can change. Everything changed when the fire benders attacked.

This is because there are many aspects of life that you have no control over, especially when it comes to other people.

Being secure in your faith is a little different. This is because you have to make a personal choice to take a step of faith. You are the one who has to choose to trust in the promises of God and live in a way that honours Him.

The thing about trusting in Jesus is -- the more you actively choose to believe in His promises and the more experience you have walking with Him, the more He will show you how undeniably secure you are in His presence. This is a security that cannot be taken from you, because He will never lead you astray. He will be the most loyal friend, the greatest comfort, the most ardent supporter, a source of strength, and a well of unfathomable love.

As well as spiritual security, we also have historical evidence of Jesus as a figure and what He did for us. He promised to never leave us, and with that promise, He has left us with the Biblical account, historical evidence, and proof of His presence and work in the lives of millions through the centuries. These things are gifts that we can lean on in times of shakiness, or doubt.

So even when other aspects of life are uneasy, you can be SURE that you are secure in Him, the unshakeable truth of His word,  and the promise that He will never leave you or forsake you.

What a relief!
