The Holy Trinity | God the Father
In the beginning God created the heavens and the earth. Genesis 1:1, NIV
For since the creation of the world God’s invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that people are without excuse. Romans 1:20
God is the Originator and Creator of the universe and He sustains everything in it, including time, space and humankind. He is omnipotent (all powerful), omnipresent (all present) and omniscient (all knowing). Though He is invisible, by observing the complexity, beauty and orderliness or creation, we can know of the presence of a sovereign God.
The Holy Trinity | God the Son
Therefore, the Lord himself will give you a sign: The virgin will conceive and give birth to a son, and will call him Immanuel. Isaiah 7:14, NIV
The thief comes only to steal and kill and destroy; I have come that they may have life, and have it to the full. I am the good shepherd. The good shepherd lays down his life for the sheep. John 10:10-11, NIV
Jesus Christ is the center of the Christian faith. He was truly a man who walked on earth 2,000 years ago. Born to the virgin Mary by the power of the Holy Spirit, He is the Son of God sent into the world to show humankind who God is. While He was on earth, Jesus remained sinless despite being tempted. Throughout His ministry, He performed many miracles, healing and teaching. Towards to end of His ministry, Jesus was subjected to all pain and humiliation, like a human, and became the perfect sacrifice for the atonement of our sins. Through his perfect obedience to God’s will, He was nailed to the Cross and died. On the third day, He resurrected and appeared to the apostles and many others. Forty days after His resurrection, Jesus ascended into heaven and is seated at the right hand of God the Father Almighty. Today we can have a personal relationship with God by believing in and accepting Jesus Christ.
The Holy Trinity | God the Holy Spirit
But the Advocate, the Holy Spirit, whom the Father will send in my name, will teach you all things and will remind you of everything I have said to you. John 14:26, NIV
The Holy Spirit is the third Person of the Holy Trinity. After Jesus Christ ascended to heaven, the Holy Spirit is sent into the world to continue witnessing about Jesus in the hearts of people. He hears, speaks, convinces, testifies, leads, guides, teaches, prompts, commands, forbids, helps and intercedes for us before God. The Holy Spirit helps believers to live out the Christian life and transforms them to become more like Jesus. The Holy Spirit lives and dwells in those who believe and accept Jesus Christ.
