1 John 2:24-25... Let what you heard from the beginning abide in you. If what you heard from the beginning abides in you, then you too will abide in the Son and in the Father. And this is the promise that he made to us--eternal life
There are few things in life that you can or even should, count on. One of the things the Bible is absolutely crystal on is the fact that God is consistent. Simply put He never changes...ever. We can't say that about us or about anything else we can see around us...but God simply is. His promises, what ever they may be are absolutely trustworthy. Always...forever. Just like He is...and was and always will be.
Meditate on that today. I know I will.
