Could it be that God is slow to arrive?

Though afflicted by me and needy, Jehovah will think of me.My help and my deliverer is you, my God, do not delay. Psalm 40:17

This would be the question that the psalmist would ask at that moment, I do not know, I can only suppose that I thought, this verse is very similar to various situations that I have spent in the years that I have lived and the few days that I have spent recently and in many moments without knowing and in other words I said exactly the same to God in prayer, I do not know if this is wrong but in my humanity I felt that I was weak, that I lacked strength and maybe faith; many t this happens to us, will it really be that God is late? or why did God allow us to pass this test? The latter is the correct question that we must ask ourselves, it is essential that we reflect on what is the function of the trials in the life of the Christian, in those who decide to put our faith and trust in the God of Israel, knowing that simply with each test God seeks that we are closer to Him to transform us in such a way that we grow to the stature of Christ; and we may be literally dying but we must know and understand that God is there by our side so that at the right moment when our strength ends he appears to give us the victory. God will glorify himself at the right time, that is why our verse can not come out of this mind; and although I am afflicted and needy, God thinks of me, my refuge and my helper is Jehovah and he will never do it!
God bless you.
