Faithful

God is faithful.  This truth is proclaimed with joy and certainty throughout the Bible.  In the CSB, the word faithful is found 149 times! The stages of life display a marathon of suffering rather than a sprint, but God shows up as faithful through all the seasons of our life.  God is so faithful that the Bible sometimes refers to believers with that label.  Consider the contrast of context in these two verses:
Psa. 26:3     For your faithful love guides me,   and I live by your truth.
Here it's His love that is identified as "faithful". That love being expressed changes the whole Christian experience. 
Psa. 30:4        Sing to the LORD, you his faithful ones, and praise his holy name. 
We can praise Him because our nature is growing from the experience of His faithfulness!  Praise God!
