As Mephibosheth discovered, life can drastically change for any of us in a day. Never let the Devil convince you that your situations will never change, your life is over, or the best days are past. God and God alone always has the final say in your life. You may not see how God can fix your situation or turn it around, but God can change everything in a day.
Proverbs 27:1 Boast not thyself of to morrow; for thou knowest not what a day may bring forth.
