If you believe in Jesus, you will not be disappointed.
1 Peter 2:6 (WEB)
Because it is contained in Scripture,
“Behold, I lay in Zion a chief cornerstone, chosen, and precious:
He who believes in him will not be disappointed.”
From the time we are born into this world until we die, we suffer disappointment. Those who put their trust in someone or something other than salvation through Jesus will suffer an eternity of disappointment.
Those of us who trusted Jesus for our salvation, will know no disappointment in Heaven. Heaven will be more glorious than we can even imagine.
Now we should seek to serve God to the best of our abilities. We should honor God with praise and worship and share the Gospel with others, while there is still time.
