Believing and trusting the LORD is beneficial to one soul, body and mind. Whatever happens, never, ever doubt the love and care that GOD has for you, you just need to believe and have faith.
Remember, GOD is not stone hearted to let you suffer in times that you need HIS help. GOD is not forgetful to forget the good things that you are doing with HIS help and will. GOD is graceful to shower you with gifts and blessings, more than you can ask for.
We may not completely understand the things that are happening to us, but regardless, you should have faith and trust in GOD that everything will fall into place.
That all sadness would turn into joy. All tears will be wept away and eventually there will be no more. That sacrifices and hardships will all be gone.
And most importantly, the longing and wishing to see the glorious moment to finally meet the Creator will soon be over.
Believe, believe just believe. Trust in GOD.
