Sin and guilt goes hand in hand. Sin cause guilt and therefor that guilt makes us feel far from God. Guilt causes us to feel sorry for ourselves and also leads to us living with a defeated mindset BUT… God has beaten sin. He has conquered death. On the cross He took ALL our sins away and that is what it means to be empowered by grace. To live in the freedom God has given us and if we make a mistake in life that causes sin to enter into our hearts, we repent and ask God for forgiveness.
God won’t cause us to feel guilty about our sin, because He loves us and won’t suppress us. The devil want us to feel guilty and therefor feel far form God. Rebuke that guilt and live in God’s freedom.
Conviction on the other hand is something else. That is when you choose to ignore something that the Spirit has laid on your heart to do and He reminds you of it. Turn back and do it, don’t live in fear if you didn’t do it. Move in faith
