I'm reminded of the scene in the garden of Gethsemane before Jesus was arrested where all of his disciples deserted and forsook him.
Matthew 26:36 (NIV)
36 Then Jesus went with his disciples to a place called Gethsemane, and he said to them, “Sit here while I go over there and pray.” 37 He took Peter and the two sons of Zebedee along with him, and he began to be sorrowful and troubled. 38 Then he said to them, “My soul is overwhelmed with sorrow to the point of death. Stay here and keep watch with me.”
39 Going a little farther, he fell with his face to the ground and prayed, “My Father, if it is possible, may this cup be taken from me. Yet not as I will, but as you will.”
40 Then he returned to his disciples and found them sleeping. “Couldn’t you men keep watch with me for one hour?” he asked Peter.41 “Watch and pray so that you will not fall into temptation. The spirit is willing, but the flesh is weak.”
42 He went away a second time and prayed, “My Father, if it is not possible for this cup to be taken away unless I drink it, may your will be done.”
43 When he came back, he again found them sleeping, because their eyes were heavy. 44 So he left them and went away once more and prayed the third time, saying the same thing.
45 Then he returned to the disciples and said to them, “Are you still sleeping and resting? Look, the hour has come, and the Son of Man is delivered into the hands of sinners. 46 Rise! Let us go! Here comes my betrayer!”
"And they all left him and fled."
And then when He was on the cross, "...Jesus cried out in a loud voice, "Eli, Eli, lema sabachthani?" (which means "My God, my God, why have you forsaken me?").
To still have faith in God despite of being or feeling forsaken is faith indeed.
1 John 5:4-5
4 for everyone born of God overcomes the world. This is the victory that has overcome the world, even our faith. 5 Who is it that overcomes the world? Only the one who believes that Jesus is the Son of God.
