Arise, go to Nineveh, that great city, and cry against it; for their wickedness is come up before me” (Jonah 1:2).
There are various signs to know that God is calling you to preach the gospel to every creature (Human being) mostly sinners.
This was the charge given to the Prophet Jonah by God. From the time of Old Testament till now God has been charging believers to arise, go and preach the gospel to everyone and all nations.
Before the ascension of Jesus Christ, He re-echoed the same charge to His disciples and by extension all Christians, “Go ye into the world, and preach the gospel to every creature” (Mark 16:15). This explains the reason why the Early Believers “went forth and preached everywhere” (Mark 16:20).
God’s charge is, arise, go. Take note, this charge is not to wait for people to come to you before you start to preach the gospel to them nor is it a command to get them first in the church before you begin to witness to them.
This also is not a charge to first specialize in deliverance, prophecies, music, worship, healing, the teaching of doctrines and prosperity teaching. It is a charge to arise from where you are and who you are and go to preach the good news.
It is a charge to arise from your comfort zone as a Christian, go where sinners are, preach the gospel of repentance to them, and be urgent about it.
WHY IS IT URGENT TO PREACH THE GOSPEL?
1 Time is short and condemnation awaits those who refuse to repent from their sins (John 9:4; 1 Corinthians 7:29-31).
2 Tens of thousands of people plunge into hell every day from all sorts of killings, sexual immoralities, uproars, terrorism and violence (Luke 13:1-5).
3 There are many sinners in the world who still have the need for salvation (Matthew 9:36; John 4:35-38).
There is an urgent need to preach the gospel with accelerated speed today than at any time in history because time is fast running out. The situation in the world is worsening, people are multiplying, distress and unrest are increasing by the minute.
So you should leave whatever thing that is occupying your time now and launch out to preach the gospel to everyone you found anywhere.
Apply every means possible to call sinners to repentance, including the use of modern technology: the internet, social media, mobile phones and so on.
Also, make a sacrifice with your time and resources that are necessary for the salvation of others. The Bible says he that wins souls is wise.
