“We often place the importance on actions that we call sin, but all sin is the result of unbelief in our hearts. God looks on the heart, and it’s the unbelief He sees. Faith is what pleases God (Hebrews 11:6). It’s always unbelief, not sin, that keeps us from receiving (Hebrews 4:2).”
(Andrew Wommack's Living Commentary)
John 16:8-11 (The Living Bible)
“And when he (The Holy Spirit) has come he will convince the world of its sin, and of the availability of God’s goodness, and of deliverance from judgment. The world’s sin is unbelief in me; there is righteousness available because I go to the Father and you shall see me no more; there is deliverance from judgment because the prince of this world has already been judged.”
John 14:6 (The Amplified Bible)
Jesus said to him, “I am the Way and the Truth and the Life; no one comes to the Father except by (through) Me.”
Hebrews 4:1-2 (The Passion Translation)
Now God has offered to us the same promise of entering into his realm of resting in confident faith. So we must be extremely careful to ensure that we all embrace the fullness of that promise and not fail to experience it. For we have heard the good news of deliverance just as they did, yet they didn't join their faith with the Word. Instead, what they heard didn't affect them deeply, for they doubted.
