People have fears about what may be coming in the world. Their fears are varied - government collapse, financial collapse, power grid failure, natural disaster, government abuse of power, nuclear war, disease, food shortage, etc. These concerns are not without some sense of legitimacy. Some people respond to these fears by becoming what is called doomsday preppers. These people stockpile food, weapons, survival equipment, etc. Some build underground structures. Prepping has become a major industry. Other people think they should take some basic precautions for a short term emergency, but not for a long term survival situation. Other people think the preppers are crazy, fringe, paranoid people. They think there is nothing one can do to prepare, or that there is nothing that should be done. It is true that it would be better to be overprepared than underprepared, but everyone should have at least some basic supplies for an emergency.
What does that have to do with our relationship with God? The biggest emergency of all time is coming, and the Bible clearly warns us about it. It is the second coming of Jesus Christ and the end of this world (Mt 24, Mk 13, Lk 17, Lk 21, 1Thes 4, 2Thes 1-2, 2Pet 3, Rev 19). The Lord warns us to be prepared for it. While we cannot be ready for every possible contingency in this life, this is one major situation we cannot ignore. We do not know exactly when it will happen, but the Bible does give us warning signs - all of which are happening now. Some Christians take the irresponsible position that we should not be concerned at all about what is going on in the world. They presume that God will take care of everything for them. They are not reading the Bible clearly, because that is not the doctrine of Jesus Christ. He warned His disciples almost 40 years early that Jerusalem would be surrounded by enemy armies just before it was to be destroyed. He gave them specific directions to escape by. He told them the parable of the 10 virgins (and others) which clearly teaches the principle of preparation for His second coming (Mt 25).
How do we get ready? If we have never put our faith in Jesus Christ as the only Savior, we need to. If we have never obeyed the gospel of the death, burial, and resurrection of Jesus Christ (1Cor 15:1-4) by repenting of sin, being baptized by immersion in water in the name of Jesus Christ, and receiving the gift of the Holy Ghost (Acts 2:38, Acts 8:12-17, Acts 10:44-48, Acts 19:1-6), then we need to do that. If we are not living a Christian life according to the scriptures, we need to do that. Salvation is like an insurance policy. We do not wait until after an accident or disaster to call an agent to get a policy. It is too late. We cannot wait until the Lord returns to start making preparations. God is very gracious and merciful, and He always gives warnings, but there is such a thing as being too late. Noah warned the people before the flood, Lot warned the people before the fire and brimstone fell, the prophets warned Israel before the nation was judged, and the Lord and the apostles have warned us about the second coming. It is up to us to be ready.
