God’s purpose is to make us like Himself – holy and pure. Ephesians 5:25-27 — “Christ loved the church and gave himself up for her to make her holy, cleansing her by the washing with water through the word, and to present her to himself as a radiant church, without stain or wrinkle or any other blemish, but holy and blameless.” (free from moral fault or guilt)
It is God’s will that that you should be sanctified: that you should avoid sexual immorality (1 Thessalonians 4:3-5 – For this is the will of God, your sanctification: that you abstain from sexual immorality; that each one of you know how to control his own body in holiness and honor, not in the passion of lust like the Gentiles who do not know God.). Purity is not only God’s will but also his purpose for our lives.
The purpose of the Father’s choosing us is “holiness” The Apostle Paul writes in Ephesians 1:4 — “For he chose us in him before the creation of the world to be holy and blameless in his sight.”
The purpose of the Son’s dying for us on the cross is “holiness” Titus 2:13-14 teaches: “Jesus Christ, who gave himself for us to redeem us from all wickedness and to purify for himself a people that are his very own, eager to do what is good.”
The purpose of the Spirit’s indwelling us is “holiness” 1 Thessalonians 4:7-8 – “For God did not call us to be impure, but to live a holy life. 8 Therefore, he who rejects this instruction does not reject man but God, who gives you his Holy Spirit.“)
The work of the triune God, Father, Son, and Spirit, is focused on one thing: To so transform us by His Spirit and Word that we reflect him and his character in all that we say, do, and think.
