Because...

Psalms 116:8 KJV

For thou hast delivered my soul from death, mine eyes from tears, and my feet from falling.

This Psalm was likely an expression of thanksgiving after an especially dangerous circumstance. If it was King David, for instance, he had any number of times when he might have been able to look back and think, "That could have turned out much worse!" Take, for instance, when fighting the brothers of Goliath, he, in his later years by then, grew weary and had to be rescued. He could have died, he could have witnessed the loss of his rescuers and he could have fallen in his weariness. Or consider David at the end of his years looking back at the whole scenario of his life. Many times he could have died. On many occasions there could have been tragic events leading to terrible years. There were times he was near to falling spiritually but God kept him through his life. 

There is a prophetic application of this that belongs to every Christian for we too have been:

Soul from death

This is salvation. None of us will ever know the death of all deaths, which is the second death when both death and hell are cast into the Lake of Fire.

Eyes from tears

Not that we have had no tears or that we will never have them again, but at the last God shall wipe away all tears from our eyes.

Feet from falling

This is prophetic of eternal security. Though there are hundreds of times in the life of every believer that, if our eternal salvation had depended upon ourselves, we would not have made it. But it doesn't depend on us. It rests in:

• The work
• The nature and
• The character

of Jesus Christ.

The Psalm begins, "I love The Lord because…." These are great reasons to love the Lord.
