Acts 15:8 - So God, who knows the heart, acknowledged them by giving them the Holy Spirit, just as He did to us, 9 and made no distinction between us and them, purifying their hearts by faith.
Therefore, since we have these promises, dear friends, let us purify ourselves from everything that contaminates body and spirit, perfecting holiness out of reverence for God.
2 Cor 7:1
Now that you have purified yourselves by obeying the truth so that you have sincere love for each other, love one another deeply, from the heart.
1 Peter 1:22
But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus, his Son, purifies us from all sin.
1 John 1:7
If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.
1 John 1:9
So there is an element of coming to faith, and what we do.
Walking in the light, obeying the truth, not doing things that contaminate us,
confessing our sins.
And our experience is our learnt behaviours, often lead us into lusts of the flesh,
and though in coming to faith much has been cleansed there is still much for us
to work through and resolve.
So Amen let us strive to live pure clean lives, Amen.
