I do not think that our blessings can be denied or stagnated. What we are blessed with and what we will be blessed with in this life is our destiny. Nothing can stop it. Maybe we can experience difficulty, hardship or misfortune along the way. That is just a mere delay and time to get closer to God and appreciate what we have once we get them.
What is yours will always be yours. Most times we do not understand the ways of God. We may think that certain blessings aren't forthcoming or that they are slipping our grip. We fail to understand that God doesn't let us have what isn't meant for us and it is just one ugly door shutting for a beautiful one.
When we don't get many things that we want, some aren't just meant to be for us. We are better off without them and that indeed is a blessing.
