[3] The difference between a prayer and a blessing

Prayer is silent speech in the 2nd person to God made on bended knees
A Blessing is public audible speech referring to God in the 3rd person made standing up.

Solomon's Inaugural Blessing and Prayer

14 Then the king turned his face and began to bless all the congregation of Israel, while all the congregation of Israel were standing up.
15 And he went on to say: Blessed is Jehovah the God of Israel, who spoke by his own mouth with David my father, and by his own hand has given fulfilment, saying, (1 Kings 8 NWT)

54 And it came about that, as soon as Solomon finished praying to Jehovah with all this prayer and request for favour, he rose up from before the altar of Jehovah, from bending down upon his knees with his palms spread out to the heavens;
55 and he began to stand and bless all the congregation of Israel with a loud voice, saying:
56 Blessed be Jehovah, who has given a resting-place to his people Israel according to all that he has promised. There has not failed one word of all his good promise that he has promised by means of Moses his servant. (1 Kings 8 NWT)

Jesus' famous prayer before he was betrayed and arrested

40 Having come to the place he said to them: Carry on prayer, that you do not enter into temptation.
41 And he himself drew away from them about a stone's throw, and bent his knees and began to pray,
42 saying: Father, if you wish, remove this cup from me. Nevertheless, let, not my will, but yours take place. (Luke 22 NWT)

The Lord's Prayer

5 And when you pray, you shall not be as the hypocrites, for they love to pray standing in the synagogues and in the corners of the open streets so that they may be seen of men. Truly I say to you, They have their reward.
6 But you, when you pray, enter into your room and shutting your door, pray to your Father in secret. And your Father seeing in secret will repay you in the open.
7 But when you pray, do not be babbling vain words, as the nations; for they think that they shall be heard in their much speaking.
8 Then do not be like them, for your Father knows what things you have need of before you ask Him.
9 So, then, you [should] pray this way: Our Father who is in Heaven, Hallowed be Your name.
10 Your kingdom come; Your will be done, as [it is] in Heaven, also on the earth.
11 Give us today our daily bread,
12 and forgive us our debts as we also forgive our debtors.
13 And do not lead us into temptation, but deliver us from the evil, for Yours is the kingdom and the power and the glory to the ages. Amen.
14 For if you forgive men their deviations, your heavenly Father will also forgive you.
15 But if you will not forgive men their deviations, neither will your Father forgive your deviations. (Matthew 6 GLT)

So we should pray to our Father in heaven, God, in secret but pray on behalf of 'us', which is all those with God as a father which is all of the sons of Abraham by covenant, all of the sons of the 1AC, all of those with faith in God. For Jehovah is the God of Abraham and Isaac and Jacob.

Who can pray to Jesus?

Jesus himself instructs us to pray to our Father, who is in Heaven. Well Jesus is the eternal father angelically of Jacob and of Adam through the ARC - see intro28, and Jesus is now a God in heaven (except when he is getting married in the ark when he is a God in the ark in the heavens of our atmosphere presumably). So any saint (angelic son of the JAC) and any adamic person with faith in Jesus can pray to him. Any non adamic Isaaic person has Isaac as a father. Isaac is alive on Eden2 - see U54 (or in the ark) with Methuselah as his CRC father - see intro28, and Methuselah was the firstborn human son of Enoch - see intro20a who was Michael - see intro16. Since Methuselah is the firstborn human son of Jesus, non adamic Isaaics can pray to Jesus. Non adamic Abrahamics have Abraham as their father and he is alive on Eden2 (or in the ark) with Adam as his father through the FBC, the Faith Blessing Covenant - see intro28. Jesus is the father of Adam through the LRC, the OMC - see intro47.

So anyone with faith in Jesus can pray to Jesus and anyone with faith in God can pray to God. But do not merely pray for yourself. Pray for all those who have Jesus or Jehovah as their God. Pray for all of your fellow worshippers, your fellow prayers, your fellow faithful.
