King Solomon described Jehovah’s kindness in the context of a deep prayer:
“Whatever prayer, whatever request for favor may be […] (for each one knows the plague of his own heart) […], then may you hear from the heavens, your dwelling place, and may you forgive and take action; and reward each one according to all his ways, for you know his heart (you alone truly know every human heart), so that they may fear you […]” (1 Ki. 8:38-40).
Fearing God in our hearts does not mean we dread God or that we flee from him.
Fear of God implies fear of letting him down, fear of disrespecting him.
Whether or not a person is sincere in their service toward God can only be judged by God himself.
One is assured, however, that regardless of what we do, God pays to each his own.
Imagine someone in a dire situation.
He calls out to God, but God sees that he is insincere.
God does not forgive him.
Not even Jehovah God, the God of all love, kindness and forgiveness, forgives him, because that person is insincere and God can see through his facade.
That would be truly dreadful.
It is different, though, when one serves God.
If you sincerely strive to do what is good because you fear displeasing God, or if you sincerely repent, you can rest assured that Jehovah will listen to your prayer and bless you according to your ways, sooner or later (Ps. 145:16; Rev. 21:3-5).
“O Jehovah the God of Israel, there is no God like you in the heavens above or on the earth beneath, keeping the covenant and showing loyal love to your servants who are walking before you with all their heart,” (1 Ki. 8:23).
