There has never been a believer who walked the earth who did not have human doubts. Having doubts does not mean that you reject Jesus. A God that is believable is not that great a God. A God who was so small as to be easily understood, is not a God worth worshipping. Our God is the only one true God and Jesus is the only path to eternity in Heaven. We receive Christ, on the basis of, repentance and faith. Repentance means to change direction from walking away from God to walking with Christ.
We choose of our own free-will out of faith to turn our back on our doubts. So that someday, we will stand before God as
His good and faithful subjects.
Jesus says to you:
“For God so loved the world, that he gave
his only Son, that whoever believes in him should not perish but have eternal
life.” – John 3:16
