Dear friend
To me the reply to your question is:
How can you know how strong your faith is?
TRUST and in trusting God to PERSEVERE
By perseverance in faith, hope, charity, mercy, works, deeds, prayer, limitless love. Perseverance in adversity, trial, injustice, attack, suffering, loss, betrayal, persecution, hatred, when all seems lost, when darkness closes around us, through doubts, tiredness, apathy, uncertainty, injury, loss of health, facing fear…the list is endless, but it is trust and perseverance and the final analysis at death is only when we will truly know how great a faith we have possessed; when we can answer, ‘Lord I have kept the faith and I fed you, I gave you drink, I clothed you and I loved you and have been kind to you, I did this to you and to the very least of these’ and He says ‘Amen, Come, the Kingdom of heaven is yours’.
God Bless you and much love and peace to you
