I really do try to think logically through this, but I'm not sure why the thought of belief is only a one time thought or action someone makes.
What is the opposition to continual belief in Christ?
Salvation is a one time event and is an action that the Lord Jesus Christ makes the MOMENT we believe(aorist tense)......Acts 16:31.
If this were not true, not a ONE of us could possibly do what God asks of us after salvation................because we need His Spirit to live the Christian way of life. If we didn't have the sealing of the Spirit and all His grace gifts......none of us could succeed in His plan.
There is no opposition to continual belief. There is opposition to ," I must continue to believe or my gift of eternal life will be revoked." Romans 11:29
