Do you have eternal security ?

I can't take credit for this, but I agree with Dr. Jeremiah completely:

In the April 23, 2010, edition of his "Turning Point" daily devotional, David Jeremiah wrote: "It would be nice to be told, when we leave on a long car trip, something like this: 'I want you to know that you are going to reach your destination safely and on schedule. Regardless of what happens en route--you may get lost, you may encounter a fierce rainstorm, and you may have a flat tire--don't worry. I am here to promise you that you will arrive.'

"We have been given such a promise by God concerning our spiritual journey. The promise comes in the form of a seal--the seal of the Holy Spirit. Paul uses language common to the ancient world. A seal affixed to documents by kings and authorities made them official and inviolable upon pain of death or punishment. No one dared to violate the terms of a document that bore an official seal. No one in the spiritual realm would dare violate the plan God has for those He has sealed. As Paul wrote, 'Who shall separate us from the love of Christ?' (Rom. 8:35) The Holy Spirit, dwelling in every Christian, is God's seal that we will make it to heaven.

"Don't let obstacles along the road to eternity shake your confidence in God's promise. The Holy Spirit is God's seal that you will arrive."
