Joel

Joel was prophesying on some tough times, comparing God's judgment of His people to a plague of locusts. He talks about the coming of a "dark and terrible day of the LORD."

However, as with all the Old Testament prophets, he also talks about repentance.

Some of the lines from Joel will be familiar to us. "Whoever calls on the name of the LORD will be saved" (Joel 2:32) and of course "I will pour out my Spirit on all men...." (Joel 2:28) is quoted by Peter at Pentecost to explain the workings of the Holy Spirit. (See, he wasn't just making it up as he went along.)

  JOEL
Vale of Decision.
Call on his name and be saved.
His Spirit will flow.

Even though God judges, he always provides a way out.
The first step is making a decision, and callling out to Him.
