Now is the time for everyone who believes in God to endure. The reason Believers are acting selfish is due to the false gospel, i.e., “it’s all about me-ism” that is taught in churches today: e.g., sit and do nothing, let us do things that please everyone and never challenges them by the words and warnings Jesus taught:

11 And many false prophets shall rise, and shall deceive many.
12 And because iniquity [by false teachers] shall abound, the love of many shall wax cold.
13 But he that shall endure unto the end, the same shall be saved.
14 And THIS GOSPEL [as found in the four gospels] of the kingdom shall be preached in all the world for a witness unto all nations [not the one taught and followed by the deceivers]; and then shall the end come. (Matthew 24)

Thus, the Gospel that JESUS taught, in its purity, must be taught again, and once the true gospel is sent through all the world, then will be the time be ripe for His return:

19 Repent ye therefore, and be converted, that your sins may be blotted out, when the times of refreshing shall come from the presence of the Lord;
20 And he shall send Jesus Christ, which before was preached unto you:
21 Whom the heaven must receive until the times of restitution of all things, (Acts 3)
