We receive salvation because we believe God.
Jesus is a promise to us of forgiveness, as expressed in the gospels. It is words of a true story that the people are testifying to.
The conditions of this belief is that we are sinners who need to be saved. Accepting this position by implication is that we repent and desire the impossible to change that only God can achieve in us.
Jesus says if we keep His words in our hearts and obey them then we are His friends.
But do you believe His words or have you created another gospel which is much more complex than taking someone at His word?
Jesus does not joke or is the issue complicated. What is complicated is our denial of sin and being honest with ourselves and the Lord.
The reason we have so much difficulty taking God at His word is because we are so bad at keeping ours and we put so many other meanings and conditions it usually is actually very different than we intended. This makes Gods direct approach very difficult for us to take seriously. All who believe on Jesus are saved. Trouble is it is difficult to take the words and put them into action. So we easily give up, compromise, stop fighting, deny, go a different road, because sin pins us down so many times it is a joke.
But if we confess, if we walk, if we stay true, then He will stay true to us.
I know many people who fear truth within and jump on the nearest con that seems ok because they do not trust God to walk with them. And this is all proof grace and no conscience is the only way to go, giving up the faith and the walk.
