Lamar Odom on the Mend -- Kim Praises God and Power of Faith

Lamar Odom continues to make progress, talking and smiling with Khloe, Kim, Kris and Kendall Jenner who made the trek back to Vegas to be with him.

Kim posted on Instagram just before midnight Saturday, "I have faith in you. I believe in the power of prayer and positive energy! Thank you for all your prayers! Lammy, I'm so happy Kendall & I could make you smile today! God is good!"

As we reported, Lamar's heart is rebounding and he's off a ventilator. He's now alert and speaking, but his condition is still dicey ... other organs are still creating problems, and doctors have not fully assessed the impact of the strokes he suffered.
