ISB ~ John 17 v3

eternal life:To possess life is to know the living God in his triune glory. Although this knowledge has a cognitive and intellectual dimension, it also includes a relational bond of love, friendship, and communion with God that grows steadily until our union with him is complete in heaven (Eph 1:17; 1 Jn 4:7).

• Personal knowledge of God is a sign of the New Covenant, according to Jer 31:33-34.

the only true God:The NT doctrine that God is a Trinity is built on the OT doctrine that Yahweh alone is God (Deut 6:4; 32:39). This ancient belief, held dear both in Israel and in the Church, stands in sharp contrast to the pagan notion that many gods exist and deserve our recognition (Ex 20:3-6; Is 43:10; 1 Cor 8:5-6).
