Luke 18:6-8

The Lord said, “Listen to what the unrighteous judge says. Won’t God avenge his chosen ones, who are crying out to him day and night, and yet he exercises patience with them? I tell you that he will avenge them quickly. Nevertheless, when the Son of Man comes, will he find faith on the earth?”

When it comes to prayer, it isn’t God who doesn’t follow through. Like I mentioned, it has everything to do with our faith. God really wants to answer us but when we pray we must come to Him in faith, really believing what He says. In other words, prayers by those who fail to believe what He says about righteousness and decide to pray knowing that they have sin in their lives, can’t expect to get an answer, because sin stops our prayer as David said about himself:

Psalms 66:18

If I cherished sin in my heart,
the Lord wouldn’t have listened.

If we pray, and don’t actually believe that He is able or willing to help us, we are being faithless in another way and we can’t expect to get anything from God.

James 1:6-8

But let him ask in faith, without any doubting, for he who doubts is like a wave of the sea, driven by the wind and tossed. For let that man not think that he will receive anything from the Lord. He is a double-minded man, unstable in all his ways.

Jesus is still going to return to the earth to rule it. It is our responsibility to maintain our faith in this fact. He could be coming very soon and we should expect that He will defend us from those who abuse us. We should not give up our prayers to escape those who persecute us. Those of us who pray for those who are persecuted should not wear out in our prayers because God will act on our behalf to His own glory in Jesus His Son.

John 14:13-14

Whatever you will ask in my name, that will I do, that the Father may be glorified in the Son. If you will ask anything in my name, I will do it.
