Are you going to invest in your doubt or are you going to put your faith in Christ? What the Bible says is true, is true. It's God's Word, and God is NOT a liar. Romans 5:8 says, "But God demonstrates his own love for us in this: While we were still sinners, Christ died for us."
Christ died for us WHILE we were still sinners, not because we did anything to deserve it. He died for us, so we could live.
John 3:16 says, "For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life."
Romans 15:7 "Accept one another, then, just as Christ accepted you, in order to bring praise to God"
Christ accepts us. We cannot be perfect here on Earth. We have flaws and Christ knows that. But he died for us so that we could be made clean. 1 John 1:9 "If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness"
Hebrews 9:14 "How much more will the blood of Christ, who through the eternal Spirit offered himself without blemish to God, purify our conscience from dead works to serve the living God."
We are not sinless here in this world. But that doesnt mean that we get to make a practice of sin.
You can ALWAYS pray to God, and ask Him for help. You can talk to him about anything. There are so many verses in the Bible telling us to seek God.
