Proverbs 27:1 Boast not thyself of tomorrow, for thou knowest not what a day may bring forth.
We should live each day as if it were our last.
The apostle Paul lived like there was no tomorrow. His plans to return to Jerusalem were risky. Chances were, he would be arrested, imprisoned, and end up losing his life. But Paul knew it was God's will.
Acts 20:24 But none of these things move me, neither count I my life dear unto myself, so that I might finish my course with joy, and the ministry which I have received of the Lord Jesus, to testify the gospel of the grace of God.
If we "sold out" for the Lord, we would find God providing our needs in greater abundance and with His resources, not ours. Focus each day to glorify God.
