God is One. We are to “love the Lord our God with all our heart and with all our soul and with all our might.”
God is three persons: God the Father, God the Son, God the Holy Spirit. Each person of God is equal to the other; we worship God as One.
Jesus says, “I know where I come from and where I am going.” (John 8: 14) “My judgment is true, for it is not I alone who judge, but I and the Father who sent Me.” (John 8: 16) “If you know Me, you know the Father also.” (John 8: 19)
“For God so loves the world that He gives His only Son that whoever believes in Him should not perish but have eternal life.” (John 3: 16) So, “Christ is faithful over God’s house as a son.” (Hebrews 3: 6)
Jesus says, “I send [the Helper, the Holy Spirit] to you. And when He comes, He convicts the world concerning sin and righteousness and judgment: concerning sin, because they do not believe in Me, concerning righteousness, because I go to the Father, and you see Me no longer; concerning judgment, because the ruler of this world is judged.” (John 16: 7 – 11)
Jesus prays, “And now, Father, glorify Me in Your own presence with the glory I had with You before the world existed. I manifest Your Name to the people whom You give Me out of the world. Yours they are, and You give them to Me, and they keep Your Word.” (John 17: 5 – 6)
The prophet Joel writes, “And in the last days it is, God declares, that I pour out My Spirit on all flesh, and your sons and your daughters prophesy, and your young men see visions, and your old men dream dreams; even on my male servants and female servants in those days I pour out My Spirit, and they prophesy. And I show wonders in the heavens above and signs on the earth below… And it comes to pass that everyone who calls on the Name of the Lord is saved.” (Acts 2: 17 – 19, 21)
