2 Sam 23:5 5Although my house be not so with God; yet he hath made with me an everlasting covenant, ordered in all things, and sure: for this is all my salvation, and all my desire, although he make it not to grow. The Salvation of man is the fruit and effect of a Everlasting Covenant counseled by the Triune God, the Father, Son, and Holy Ghost Ps 33:11 11The counsel of the LORD standeth for ever [sure], the thoughts of his heart to all generations. The LORD here is the Elohim, the Triune Jehovah, and their counsel and thoughts are one. The proper scheming of the Salvation of men was first and foremost for the Glory of God leading to the comfort and happiness of their Chosen ones Ps 33:12 12 Blessed is the nation whose God is the LORD; and the people whom he hath chosen for his own inheritance. [1 Pet 2:9] And so the counsel was convened in regards to the Great importance of Salvation. For all their Perfections were to be manifested, especially the Wisdom of God Eph 3:4-11 4Whereby, when ye read, ye may understand my knowledge in the mystery of Christ) 5Which in other ages was not made known unto the sons of men, as it is now revealed unto his holy apostles and prophets by the Spirit; 6That the Gentiles should be fellowheirs, and of the same body, and partakers of his promise in Christ by the gospel: 7Whereof I was made a minister, according to the gift of the grace of God given unto me by the effectual working of his power. 8Unto me, who am less than the least of all saints, is this grace given, that I should preach among the Gentiles the unsearchable riches of Christ; 9 And to make all men see what is the fellowship of the mystery, which from the beginning of the world hath been hid in God, who created all things by Jesus Christ: 10 To the intent that now unto the principalities and powers in heavenly places might be known by the church the manifold wisdom of God, 11 According to the eternal purpose which he purposed in Christ Jesus our Lord: This Great Work was entrusted into the Hands of the Son Jn 17:4 4I have glorified thee on the earth: I have finished the work which thou gavest me to do. Then He became Surety for all whom God would be Glorified in saving from the ruin of the Fall. Heb 7:22 22By so much was Jesus made a surety of a better testament. Since all Three Beings of the One Godhead counseled in this momentous matter of Salvation, thats why we have one of the most hated scriptures in the NT that points to the Triune God 1 Jn 5:7 7For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one. Also Isa 48:16 appears to confirm the scheme of the Triune God, and the Son being sent to fulfill His Covenant obligations 48:16 16Come ye near unto me, hear ye this; I have not spoken in secret from the beginning; from the time that it was, there am I: and now the Lord GOD, and his Spirit, hath sent me. also the Son speaks here Ps 40:7-10 7Then said I, Lo, I come: in the volume of the book it is written of me, 8I delight to do thy will, O my God: yea, thy law is within my heart. 9I have preached righteousness in the great congregation: lo, I have not refrained my lips, O LORD, thou knowest. 10I have not hid thy righteousness within my heart; I have declared thy faithfulness and thy salvation: I have not concealed thy lovingkindness and thy truth from the great congregation. Yes Salvation is the result of Covenant Faithfulness from the Triune God, May His Perfections be Adored forever !
