1 Nephi 18:15-16

And it came to pass that we were about to be swallowed up in the depths of the sea. And after we had been driven back upon the waters for the space of four days, my brethren began to see that the judgments of God were upon them, and that they must perish save that they should repent of their iniquities; wherefore they came unto me, and loosed the bands which were upon my wrists, and behold they had swollen exceedingly; and  also mine ankles were much swollen, and great was the soreness thereof.
Nevertheless, I did look unto my God, and I did praise him all the day long; and I did not murmur against the Lord because of mine afflictions.

Its never too late to call upon the Lord.
