Paul writes about this in 2 Corinthians 6:2 when he says, "I tell you, now is the time of God's favor, now is the day of salvation." [emphasis mine]. Here we can see that there is some sense of urgency in what Paul is saying. Each day we have is an opportunity to come to Him, and God is keeping this door open for an unknown period of time. While we have a chance, it is in our best interest to come to Him, because there is a day of judgement that is coming.
Jesus confirms this when His disciples ask Him about the end of the 'age' and what will be the signs. He parallels it to the days of Noah. He says in Matthew 24:37-39 (fuller passage posted at the end):
God has now 'opened' the door of salvation through His Son, Jesus Christ, and is commanding that all mankind repent of their sins and trust His Son for salvation from the judgement that is to come. Today is that day. Now is the time, as Paul writes. For believe this that God will certainly come to judge the world in righteousness. The Bible is very clear.
I pray that if you have not yet taken advantage of God's 'Open Door' policy that you would do so. Because there will be a day when God closes that door and those who have not accepted will be cast into hell. But God is gracious and is giving us all an opportunity for salvation today.
Won't you consider what God has done before the time is too late? I pray you will. But don't take my word for it, read all about it for yourself in God's Word.
