L3 which stands for Level 3 support is the highest level of support in a technical support model. The ones who provide L3 support are subject matter experts that are engaged to address and solve problems that are unsolvable by others in the support line.

Jesus Christ is an L3 God. When the world could not solve the problem of sin that plagued man, He did. He is the subject matter expert of man, because He made man and knows all men and knows what is in man (John 2:24-25).

The Psalmist avers that the eyes of the Lord are upon the righteous (God is looking; Psalm 34:15), and his ears are open unto their cry (God is listening; Psalm 34:15). The righteous cry and the Lord hears them and delivers them out of all their troubles (God is liberating; Psalm 34:17).

Jesus is Looking, Listening and Liberating (L3). Jesus Christ is a L3 God.

Psalm 34:15, 17 (KJV)
15
The eyes of the LORD are upon the righteous, and his ears are open unto their cry.
17 The righteous cry, and the LORD heareth, and delivereth them out of all their troubles.
