We might feel discouraged or uncertain about our salvation. Get rid of the sin. But if you step back, the picture is clear, beautiful and simple. God knows what He is doing.
Perseverance always gives birth to hope.
God promises us many things, salvation being our ultimate prize. This is what perseverance leads to. Life will be a test. It is like a selection program, only you already have the qualifications. God freely gives us everything we need.
