God wants us to rely on Him. Totally, rely upon Him.
There are many examples in life today, in the past and in the Bible that examplify people and their lives getting "down to the wire."
Being boxed in, and with no where else to go and no help in sight is a desperate feeling. All appears to be lost.
David felt this, every time Saul tried to take his life. Elijah was convinced that he was the only Godly prophet left in Israel and he begged God to kill him before Queen Jezebel did. In actual fact, there were about 300 prophets of God hiding in caves, so Elijah wasn't really alone.
Joseph likely felt this when he was told by Mary, his bride to be, that she was expecting. Especially when he knew that the child wasn't his. Fortunately, an angel was able to help Joseph get everything sorted out.
Jonah knew about this. God instructed him to go and preach to the city of Ninevah and instead of doing what God told him to do he book passage on a boat in the opposite direction and as far away as possible. God wasn't going to let him off easily. He sent a storm that was so violent that the only way the sea calmed was for the crew to throw Jonah overboard.
God didn't stop there, because He knew that Jonah needed to spend some time in solitary confinement. So...Jonah spent 3 days inside a whale, getting his eyes set on God and his heart too. Only when Jonah came around to God's way of thinking did the whale spit him up. Where did he land? Right at Ninevah. No choice but to go ahead and tell the wicked people of Ninevah to change their ways and repent.
Jonah knew all about being down to the wire.
When it comes to our lives, we make mistakes, just as people have made in the past. If we keep our trust in God, our eyes and hearts focused on God too, then our difficult times may not seem as hard to bear. God will direct us if we allow Him full control of our lives.
