1 Corinthians 4:5
Therefore form no premature judgements, but wait until the Lord returns. He will both bring to light the secrets of darkness and will openly disclose the motives that have been in people's hearts; and then the praise which each man deserves will come to him from God.
2 Corinthians 1:12
For the reason for our boasting is this--the testimony of our own conscience that it was in holiness and with pure motives before God, and in reliance not on worldly wisdom but on the gracious help of God, that we have conducted ourselves in the world, and above all in our relations with you.
Ephesians 2:10
For we are God's own handiwork, created in Christ Jesus for good works which He has pre-destined us to practise.
1 John 3:7
Dear children, let no one lead you astray. The man who acts righteously is righteous, just as He is righteous.
1 John 3:10
By this we can distinguish God's children and the Devil's children: no one who fails to act righteously is a child of God, nor he who does not love his brother man.
