Does someone need to use Jesus’ name to be heard by the Almighty?

There are many examples in the Bible where people’s prayers were heard by the Almighty, before the Messiah gave his life as a corresponding sacrifice. King David is an excellent example. Abraham, Job, and Noah were among those considered righteous by God. They did not need a perfect sacrifice in order to have their prayers heard by the Almighty. God will hear the prayers of those who whole-heartily search for him. The passage at John 14:6 primarily deals with those who will rise at Christ’s return and take their proper place in God’s kingdom. Jesus is talking about preparing places for them. But he has to leave first then come back – John 13:36 – John 14:6; Zechariah 3:1-9; Revelation 6:9-11. God’s kingdom, once the “Bride” is complete and is “married” to Jesus, replaces Satan and his bride “Babylon the Great” when it comes down from heaven (Rev.21) Of course, all who desire to be saved will be no matter their position in the new world under God’s kingdom. This is only by the sacrifice of the Lamb of God, Jesus (Rev. 5:6-10; 7:9-10). Thus, this passage at John 14:6 can be properly viewed to involve all those who submit to God’s kingdom (Psalms 2). But it does not mean that someone has to use Jesus’ name in a prayer, for the Almighty to hear it. Otherwise, why didn’t Jesus teach his followers to include this thought while instructing them how to pray, as found in Matthew 6?
