Psalm 51:10-12

Create in me a clean heart, O God,
    and renew a right spirit within me.

Cast me not away from your presence,
    and take not your Holy Spirit from me.

Restore to me the joy of your salvation,
    and uphold me with a willing spirit.

Matthew 7:7-8

“Ask and it will be given to you; seek and you will find; knock and the door will be opened to you. For everyone who asks receives; the one who seeks finds; and to the one who knocks, the door will be opened.”

Matthew 5:43-48

You have heard that it was said, ‘Love your neighbor and hate your enemy.’ But I tell you, love your enemies and pray for those who persecute you, that you may be children of your Father in heaven. He causes his sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous.

If you love those who love you, what reward will you get? Are not even the tax collectors doing that? And if you greet only your own people, what are you doing more than others? Do not even pagans do that? 

Be perfect, therefore, as your heavenly Father is perfect.

1 John 4:18

There is no fear in love. But perfect love drives out fear, because fear has to do with punishment. The one who fears is not made perfect in love.
