Doubt struggles; belief overcomes.

If you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved. For with the heart one believes unto righteousness, and with the mouth confession is made unto salvation. Romans 10:9-10 (NKJV)
Believing comes from the very depths of who we are. Believing is not rooted in what we know in our heads, but in what we have embraced with our hearts.
The truth we believe is the solid foundation we build our lives upon. It is the anchor point of our faith that keeps us from drifting or being pulled away by the strong currents of doubt and unbelief.
In 2 Corinthians 4:13 we read, “I have believed, and therefore have I spoken.” That should be true of each of us. It is important for us to know what we believe and to confess what we believe.
Too often we hear others speaking what they doubt rather than what they believe. As believers, we stand upon the truth of God and declare it to be so in our lives—we whisper it in the secret places of our hearts, and with our voices, we shout it out upon the rooftops of our faith with confidence, clarity, and conviction.
Doubt draws us away from the heart of God; belief draws us near.
Doubt struggles; belief overcomes.
Doubt holds back; belief surrenders.
Doubt says, “I’m not sure”; belief says, “I know and am persuaded”.
Doubt lives in the shadows; belief steps into the light.
Doubt blocks the flow; belief brings the overflow.
Doubt holds us back; belief moves us forward.
Doubt makes us shaky; belief puts us on solid ground.
Doubt leaves us as spiritual paupers; belief brings us into our spiritual riches in Christ.
