Lamentations 3 New International Version

² Because of the Lord’s great love we are not consumed,
    for his compassion’s never fail.
²³ They are new every morning;
    great is your faithfulness.
²⁴ I say to myself, “The Lord is my portion;
    therefore I will wait for him.”

²⁵ The Lord is good to those whose hope is in him,
    to the one who seeks him;
²⁶ it is good to wait quietly
    for the salvation of the Lord.
²⁷ It is good for a man to bear the yoke
    while he is young.

No doubt you like I have had many times where we have had cause to doubt our faith and this can sometimes make us feel quite down.

What we have to remember in situations like these is that the Lord is with us ‘though we may not think or feel his presence at the time’ guiding us.

If we loose faith in God especially, in order to get it back we have to come to him in prayer, because our God is a faithful God. This is only one of the hymns I turn to at times like these as I think the words are just beautiful.

Great is Thy Faithfulness, O God my Father
There is no shadow of turning with Thee
Thou changes not, Thy compassions, they fail not
As Thou hast been, Thou forever will be

Great is Thy faithfulness
Great is Thy faithfulness
Morning by morning new mercies I see
And all I have needed Thy hand hath provided
Great is Thy faithfulness, Lord, unto me

Summer and winter, and springtime and harvest,
Sun, moon and stars in their courses above,
Join with all nature in manifold witness
To Thy great faithfulness, mercy and love.

Pardon for sin and a peace that endureth
And Thine own dear presence to cheer and to guide
Strength for today and bright hope for tomorrow
Blessings all amine, with ten thousand beside

Great is Thy Faithfulness
Great is Thy Faithfulness
Morning by morning new mercies I see
And all I have needed Thy hand hath provided
Great is Thy faithfulness, Lord, unto me
