Your prayer reflects a deep love for the church and for those who suffer in a broken world, and it is right to bring these burdens before the Lord. Jesus himself told us to pray that the Lord of the harvest would send out workers into his harvest, because the need is great and the workers are few, and what you have asked is in keeping with that call.
Scripture shows that the work of true laborers is to build up the body of Christ. The gift of speaking God's truth is given for edification and exhortation and comfort, so that the church is strengthened and encouraged and drawn closer to Christ. That is the pattern for faithful ministry in any place, whether in times of peace or in regions shaken by war, earthquake, flood, storm, famine or persecution. Wanting to prepare in advance, as Joseph was given wisdom to store up in years of plenty for years of need, and as Jesus said he told his disciples beforehand so they would believe when it came to pass, is a wise and biblical desire.
Part of that preparation is learning how God wants his people cared for. The Bible teaches that the first responsibility for widows rests with their own family, with children and grandchildren. The church also has a calling to care for those in need within the body, and the example in Acts shows the early believers organizing help for widows. But the church's special care is for those who are truly alone, described as desolate, trusting in God and continuing in prayer night and day, without family to support them. When the church helps provide for them, it is also fitting that they serve the Lord and his people in return, and that younger widows be encouraged toward a fruitful and accountable life rather than falling into idleness and gossip. In the same way, pure religion before God includes looking after orphans and widows in their distress, and raising up homes and schools that hold fast to sound doctrine. The goal of all such teaching is love from a pure heart and a good conscience and a sincere faith, and those who labor in the word and doctrine are worthy of honor.
You are also right to ask for protection from deception. The greatest danger to the church is often not from outside attack but from corruption within. From the beginning there have been false teachers who claim to know God but deny him by their lives, who have a form of godliness but deny its power, who are carried about like clouds without water. Jesus warned to take heed that no one deceive us, and the apostles warned that evil people and impostors will go from bad to worse. The way to discern is often by their motives, especially a love of money and a desire to use godliness for gain, while true servants seek to feed and strengthen the flock. The safeguard God has given is his Word. We are called to be diligent to present ourselves approved, handling the word of truth accurately, being washed and sanctified by the word of Christ, which cleanses and keeps us from the lies of the enemy. That enemy is the father of lies and the ancient serpent who accuses and deceives, and we overcome him by the blood of the Lamb and the word of our testimony, holding fast to eternal life even when facing suffering and death.
History shows that persecution itself has never destroyed the true church. Instead it separates what is real from what is false and draws believers together in love and mutual support, and the gospel spreads more widely through it. Jesus promised that the gates of hell will not prevail against the church he builds. He has not taken us out of the world, but he keeps us from the evil one as we carry the gospel forth. Our prayer therefore should be that the word of the Lord would run swiftly and be glorified, that it would be received, and that God's people would be delivered from evil and unreasonable people, and from the evil one himself.
So we join you in praying that the Lord would raise up faithful men and women, young and old, poured out upon by his Spirit, who will worship in truth, study the Scriptures, preach and teach with faithfulness, and plant and strengthen churches that hold to true doctrine. We pray that he would provide for the needy according to each one's ability, sent through faithful hands to those who truly have no other support, that he would guard all his people from fear and falsehood, and that he would make his church ready through the righteous lives of those made holy in Christ, speaking his word with boldness until he comes.
