He has ordained our peace. (Isaiah 26:12)
But we aren't just promised peace on the other side of eternity. Isaiah tells us how we can experience and walk in strength and peace today:
"You keep him in perfect peace
whose mind is stayed on you,
because he trusts in you.
Trust in the LORD forever,
for the LORD GOD is an everlasting rock." (Isaiah 26:3-4)
The Hebrew word for the phrase stayed on is סָמַך ְ (sa makh), which means "to brace, uphold, support." In other words, those with minds fully braced, upheld and supported by truth and trust in God will be kept in perfect peace. The English phrase "perfect peace" means an "all-embracing peace." It is God, by the power of His indwelling Spirit, giving us the strength internally to face whatever comes our way externally.
Ephesians 3:16 I pray that out of his glorious riches he may strengthen you with power through his Spirit in your inner being,
This doesn't mean our circumstances will feel peaceful. It doesn't mean all our relationship troubles and hardships suddenly get better. Nor does it mean that all the prayers we pray suddenly get answered. But what it does mean is that our mind can be steadied with truth instead of overrun with thoughts of fear, anxiety and worst-case scenarios.
Isaiah 26:19 But your dead will live, Lord; their bodies will rise - let those who dwell in the dust wake up and shout for joy -
The Old Testament had a shadowy understanding of the life to come, because the secrets of the life to come have now been revealed by the appearing of our Savior Jesus Christ, who has abolished death and brought life and immortality to light through the gospel (2 Timothy 1:10). But here is a confident expectation of resurrection and glory for the LORD’s righteous ones.
The great new is that we begin the resurrected life when we receive Christ and allow Him to rule and reign in our lives now!
Ephesians 2:4-5 (NASB) But[a] God, being rich in mercy, because of the great love with which he loved us, 5 even when we were dead in our trespasses, made us alive together with Christ—by grace you have been saved--
We need to wake up and shout for joy!
