1 John 1:9
If we confess our sins, He is faithful and righteous to forgive us our sins and to cleanse us from all unrighteousness.
Jesus is a merciful and gracious God who desires a relationship with you (John 14:23). It can only happen when you put your faith and trust in Jesus Christ as your Lord and Savior (John 3:16). The byproduct of a saving faith is living a life that’s according to His will through His Word for His glory (James 2:17). The moment we sin against the Lord, we break that pure relationship (not salvation wise) because we are doing something that displeases Him, and we have to repent of that sin to be in good standing once again with Him. Whenever we do sin, He waits expectantly for us to repent because He takes great joy and pleasure in using His creation to participate in His will. Especially, when believers are walking according to His righteousness, by obeying what the Scripture teaches.
Here is an illustration of how forgiveness would look like. You are in a classroom and you happen to have a handful of candy sprinkles. You decide to throw all of them at once into your mouth and when you do, only a few make it in and the rest fall to the floor making such a mess. Out of embarrassment, you look away from the teacher and your classmates. Someone comes in and cleans it all up for you that when you take a magnifying glass for curiosity’s sake to see how many sprinkles might have still been left, to your amazement, not even an iota (an extremely small amount) of sprinkle can be found.
The sprinkles represent your sins and when you repent, all of them are picked up and thrown away so that your area around you (your life) is clean once more. This is how easy it is for the believer to be forgiven by the Father whose very desire is to forgive because He loves us so much in such a capacity we can never truly understand. Remember, that when you have some grievance or animosity towards someone, resolve to fix it immediately or else God won’t use you or forgive your sins. Doing so serves as a testimony to that person because when you forgive (even though it might be entirely his fault), he might see Christ in you.
