The heart is more deceitful than any other thing, and it is also perverse. Who can uncover its secrets? I, the Lord, search the heart and probe the mind to reward all according to their conduct and as their deeds deserve.
My son, concentrate attentively on my words; pay heed to the instructions I pass on to you. Do not let them slip from your mind; keep them forever in your heart.
Hear, O Israel, the Lord, our God, is Lord alone. You shall love the Lord, your God, with all your heart, and with all your soul, and with all your might.
My son, do not forget my teaching, but cherish my commandments in your heart, for they will bring you length of days, more years of life, and an abundance of prosperity.
Do not worry about anything, but present your needs to God in prayer and petition, with thanksgiving. Then the peace of God, which is beyond all understanding, will guard your hearts and your minds in Christ Jesus.
