HE WHO HAS EARS

"He who has an ear, let him hear what the Spirit says to the churches. He who overcomes shall not be hurt by the second death."    Revelation 2.11

The phrase: 'He who has an ear...' doesn't seem to make sense, since everyone has ears. However, the Lord is speaking to those who are born of the Spirit. Only those who are born of the Spirit have ears that are able to listen to His voice. And in the case of those who are convinced but aren't born of God, they will not have an excuse when Judgement Day comes because they had ears and did not obey. Those who overcome are not the ones who start out well, but they finish well.

FAVOR FROM THE LORD

"Blessed are those who listen to me, watching daily at my doors, waiting at my doorway. For those who find me find life and receive favor from the Lord." Proverbs 8:34-35

Those who heed to the Word of God and receive it with all of their heart, allow it's Spirit into their life and it guides them throughout their journey.
Because those who find me, find life and receive favor from the Lord.

AFFLICTION

"He delivers the poor in their affliction and opens their ears in oppression." Job 36:15

If the man hadn't been born blind, he wouldn't have known the Lord Jesus.
If there wasn't a Goliath, David wouldn't have been who he was.
God allows certain afflictions and oppressions, so that mankind can keep their ears open to His voice.
