Just like the Bible has stated, as His children, we must not allow the devil to take part in our life as making us anxious and putting us in doubt . We mostly get to doubt God whenever we get ourselves in a situation that we don't like, we tend to doubt if God is still by us or not, we give Satan space to dwell in the spirit of anxiety and doubt at that moment.
If we truly read the scriptures, we should know that God said all days won't be rosy , definitely there are days that that's won't go well with us, we should not fear , instead come closer to God, trust God more than only He can take that moment away, He is masterpiece behind every situation and happenings, He can take life and can revive lives
As His children, we shouldn't let our situation take us away from God's commandments for us, we shouldn't go into sin because of what we are facing, what we are going through, disciples of God in bibles face more than that but those who stick with Him , rejoice in the end ,cos they have more than enough at athe end.
We must have faith in God till our last breath, because the faith will give us peace of mind which will be free from any harm .
