The Apostle John makes it clear your understanding needs improvement.
1 John 5:12-13
12 Whoever has the Son has life; whoever does not have the Son of God does not have life.
13 I write these things to you who believe in the name of the Son of God so that you may know that you have eternal life.

Here is my point. Today you know you have Eternal Life.
Tomorrow maybe you will suffer like Job and unlike Job you will curse The Lord. I'm not saying you will, but, The Lord gives us a choice. The choice is not made only once it is made continually.
In the Garden of Eden God told Adam and Eve to not eat the fruit but gave them the ability to disobey, He gave them agency.
You can give your life to The Lord, you can praise Him and follow Him every day and you do well to do so but, you must endure to the end or it may all be for naught.
“You can give your life to The Lord, you can praise Him and follow Him every day and you do well to do so but, you must endure to the end or it may all be for naught.”
You left out His Words about being sealed by the Spirit as a pledge. About having eternal life. About *all* sins being forgiven. About being the righteousness of Christ.
This is eternal life. Not a feeling, nor a change in feelings.
I am His. He is mine. He holds me in His hand and will lose none.
