In Mark 10:18, Jesus explicity denied he was God - Trinity Delusion

Since there is only one true God, Jesus was necessarily referring to HIS God. Consider the implications of that undeniable fact. Jesus informs us that the teachings he taught and things he did were not from himself but from the Father abiding in him. No one is good but God alone. Someone called Jesus "Good TEACHER." Jesus responded, "Why do you call me good? For that reason he said "no one is good but God alone." Jesus said, "No one is good but God alone" because he knew this good teaching was not his own but his Father's. John 7:15-17. He declared this on several occasions.

And even though Mark 10:18 concerns Jesus' good teaching and not his the goodness of his morality, this Messianic Psalm enlightens that matter as well:

A Messianic Psalm
Preserve me, O God, for I take refuge in You.
2 I said to the Lord, “You are my Lord;
I HAVE NO GOOD BESIDES YOU.”
3 As for the saints who are in the earth,
They are the majestic ones in whom is all my delight.
4 The sorrows of those who have bartered for another god will be multiplied;
I shall not pour out their drink offerings of blood,
Nor will I take their names upon my lips.
5 The Lord is the portion of my inheritance and my cup;
You support my lot.
6 The lines have fallen to me in pleasant places;
Indeed, my heritage is beautiful to me.
7 I will bless the Lord who has counseled me;
Indeed, my mind instructs me in the night.
8 I have set the Lord continually before me;
Because He is at my right hand, I will not be shaken.
9 Therefore my heart is glad and my glory rejoices;
My flesh also will dwell securely.
10 For You will not abandon my soul to Sheol;
Nor will You allow Your Holy One to undergo decay.
11 You will make known to me the path of life;
In Your presence is fullness of joy;
In Your right hand there are pleasures forever.

Note how verses 8-11 are quoted at Acts 2:24-28 to refer to Jesus.
