A recent song asks the question, "What Do I Know of Holy?" I began to think that God calls us to be holy, but what do we know of holy? God is holy (I Peter 1: 15-16; Romans 1:7; I Corinthians 1:2; Ephesians 1:4). When we speak of the 'Holy Spirit", we're saying the Spirit is holy. If we are 'indwelt' and even 'filled' with the Spirit, does it mean holiness is in us? But what is holiness? Following the law? A saintly countenance? Churchly achievement? Excellent performance? Good deeds? Being super nice to everyone?
The holy life is simply living as someone who belongs to God and who lives by the vision of the Kingdom of God. Were it only that simple. For we, on our own, don't have much to work with. We can't rightly envision what a life of holiness is, and even if we could, we couldn't get ourselves to be that way. So, the Spirit brings us into the holiness of Jesus. Thanks to the Spirit working through your faith, Jesus is really there with you and within you, giving you Jesus' holiness. It is given to us by God's grace.
Some emphasize biblical standards of holiness. Sometimes it becomes legalism. Firmer roots come when we admit we are broken creatures. Even our vision of what makes for holiness is marred and twisted. We are strangers to God's ways. We must pray for the Spirit's leading. Without the Spirit's work, we not only cannot know God, but we also fail to discover our true selves. The Spirit, through the Bible, shows us what a God-pleasing life is, and leads us to want to live it and treasure it.
If you need Godliness, only God has it, so only God can give it to you. It's all because of what Christ has done. Else what would I know about holy.
