"O the happiness of those that are merciful, since they will be shown mercy." (Matthew 5:7)
"O the happiness of those who are pure in heart, since they will see God." (Matthew 5:8)
If you are merciful to others, God will be merciful to you. He will give you his Son, so that you who are toiling and loaded down, may be REFRESHED, even as he says:
"Come to ME, all you who are toiling and loaded down and I will REFRESH you. Take MY yoke upon you and learn from ME, for I am mild-tempered and LOWLY in heart, and you will find refreshment for your souls. For my yoke is kindly, and my load is light." (Matthew 11:28-30)
All of us are lacking in wisdom and being in this world, ALL of us NEED refreshment. Religion, men, the world and everything in it has beaten us down. There is One whom we ALL may come to and find "rest" if we truly want it. He is "not far off from any one of us" (Acts 17:27; Jeremiah 23:23).
If you are merciful to others, he, out of the immense KINDNESS of his heart will be merciful to YOU. If you 'call out' for him, and give forth your voice, he will come to you, and he will open your ears, that you may hear him. In that day you will see the GREAT mercy he has for you, and you TRULY will be happy. Your happiness will be so great that NO ONE can take it away from you. In that day you will KNOW that He is in union with his Father, and his Father is in union with him, and he is in union with YOU, and YOU are in union with Him (John 14:20). He will make his words KNOWN to you and you will come to 'know' him (Proverbs 1:23).
He said, "Sanctify them by means of truth; your word is truth. Just as you have sent me forth into the world, I also have sent them forth into the world. And I am sanctifying myself in THEIR behalf that they may be sanctified by means of truth." (John 17:17-19)
We are held sacred by means of truth. The Christ, the 'word' of God, is the truth. He sanctifies himself in OUR behalf that we may be sanctified by means of him. Therefore, let us go forth to him and receive from his fullness; for he is FULL of undeserved kindness and truth, and he adds NO pain with it (John 1:14; Proverbs 10:22; James 1:5).
