Sermon: The Holy Trinity Pt. 3 - Faith Seeking Understanding

The Holy Trinity Pt. 3 – Faith Seeking Understanding Sunday, June 15th, 2025 Christ Covenant Church – Centralia, WA Deuteronomy 29:29

Prayer

Father, we thank you for the mystery of our salvation, the mystery of who You are as Father, Son, and Holy Spirit. As we seek now to understand just a small fragment of that mystery by studying the Scriptures, we ask for light to dispel the darkness of ignorance and sin. For we believe what the Lord Jesus taught saying, ‘blessed are the pure in heart, for they shall see God.’ Grant us such purity and reverence for Your Word now, in Jesus’ name, Amen.

Introduction

For the last two Sundays, we have been attempting to climb the most difficult mountain in all of Christian doctrine. That is, the mystery of the Holy Trinity. How is God One, and yet Three in One? How are the three divine persons really distinct, and yet each the One Divine Essence. This has been our study and meditation for the last two weeks, and this morning since it is Trinity Sunday we shall have one more attempt at grasping this truth.

• Now whenever you are attempting something difficult and strenuous, it is helpful to remind yourself why you are doing this hard thing in the first place.
  • I remember long ago sitting in my high school calculus class and wondering why am I here? How is calculus going to help me get a job? What do derivatives have to do with my life?
  • And because I did not have Professor O’Dell as my teacher, I dropped out of calculus, only to have to retake it later in college (even then I think I got a C).
    • I imagine most of us in this room have a similar story, perhaps not with math but in some other area of life.
• If we don’t see or understand the reason why, the purpose of doing a hard thing, we are tempted to give up, or we never even try. And sadly, that is how a lot of people approach their relationship with God.
  • They think that God is so high up there, and I am so low down here, the Bible is such a long and big book, and my attention span and memory is so short, therefore it would be either pride or presumption, folly or fruitless to attempt to try to really get to know Him.
    • And indeed, there are many dangers to avoid if you want to know God. God himself warns of approaching Him without fear and reverence and humility.
  • And yet, that high and glorious God has come down to us in Jesus Christ so that we might know him and have a real living personal relationship with him. Moreover, he has come down and sent the Holy Spirit into our very hearts. He has bequeathed to the church the Scriptures through which He invites us, nay commands us, to search him out and know Him.
    • It says in Psalm 105:4, “Seek the Lord, and his strength: Seek his face evermore.”
    • And in Jeremiah 29:13, “And ye shall seek me, and find me, when ye shall search for me with all your heart.”
    • Paul prays for the church in Colossians 1:10, “That ye might walk worthy of the Lord unto all pleasing, being fruitful in every good work, and increasing in the knowledge of God.”
• Why do people climb mountains? Why do people attempt hard, dangerous, and difficult things? They do it for the glory. For the views from the top. If they are virtuous, for the formation of character.
  • Even those who only do it for the thrill or the excitement or the vanity of social media have made a value judgment, that the risk is worth the reward, the pain is worth the p
