Believers are well aware of the boundaries God has set for us or they should be. We have the Word of God and the Spirit of God which teach us the will of God for our lives.
Problems arise when we choose to step over God's boundaries and go off into sin. The fact is, we all stumble, but none of us have to. We do it out of personal choice.
James 1:13-14 Let no man say when he is tempted, I am tempted of God: for God cannot be tempted with evil, neither tempteth he any man: But every man is tempted, when he is drawn away of his own lust, and enticed.
In truth, it’s the mercy of God that all believers haven't been caught in our sins. Imagine for a moment that the Lord allowed every thought you’ve ever had to be played in full color and stereo for the world to see and hear. You say, but thoughts are different. Are they? To think it is a sin! To do it is merely another sin.
Jesus was always honest with sinners. He didn’t pretend their sins did’t exist. Second, He always loved them and forgave them. Third, He always treated them with respect and love.
