Just how important is what I say to myself? Psalm 15 answers that question in a profound way that makes me very excited to continue teaching my current Sunday school series on Gospel Self-Talk:
Psalm 15:1 <A Psalm of David.> LORD, who shall abide in thy tabernacle? who shall dwell in thy holy hill? 2 He that walketh uprightly, and worketh righteousness, and speaketh the truth in his heart.
A comparison of Psalm 15:1-2 with two key NT statements about the gospel provides us with vital instruction:
Eph 1:13 In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise,
Colossians 1:5 For the hope which is laid up for you in heaven, whereof ye heard before in the word of the truth of the gospel;
Because Ephesians 1:13 and Colossians 1:5 both say that the gospel of our salvation is the word of truth, putting together the teaching of Psalm 15:1-2, Ephesians 1:13, and Colossians 1:5 shows us that speaking the truth of the gospel in my heart is an essential activity for me to be a person who will abide in God’s tabernacle and dwell in His holy hill!
The fullness of my experience of blessed fellowship with God is contingent upon my speaking the truth of the gospel in my heart!
