Proverbs 27:1 Do not boast about tomorrow, for you do not know what a day may bring.

James 4:13-17 Now listen, you who say, “Today or tomorrow we will go to this or that city, spend a year there, carry on business and make money.” (14) Why, you do not even know what will happen tomorrow. What is your life? You are a mist that appears for a little while and then vanishes. (15) Instead, you ought to say, “If it is the Lord’s will, we will live and do this or that.” (16) As it is, you boast in your arrogant schemes. All such boasting is evil. (17) If anyone, then, knows the good they ought to do and doesn’t do it, it is sin for them.
For me there is another application of this truth. It is too easy to think: I have plenty of time – I can do that tomorrow! It might be meeting with fellow believers, obeying God in something or other, reading the Bible or praying. An opportunity missed is an opportunity lost!
An English proverb says: Don’t put off until tomorrow what you can (or should) do today!
Psalms 95:6-7 Come, let us bow down in worship, let us kneel before the LORD our Maker; (7) for he is our God and we are the people of his pasture, the flock under his care. Today, if only you would hear his voice,
